+## 0.5.0
+
+Released on 23/05/2021
+
+> 🌸 Spring Update 2021 🌷
+
+- **Synchronized browsing**:
+  - Added the possibility to enabled the synchronized brower navigation
+    - when you enter a directory, the same directory will be entered on the other tab
+    - Enable sync browser with `<Y>`
+    - Read more on manual: [Synchronized browsing](docs/man.md#Synchronized-browsing-)
+- **Remote and Local hosts file formatter**:
+  - Added the possibility to set different formatters for local and remote hosts
+- **Work on multiple files**:
+  - Added the possibility to work on **multiple files simultaneously**
+  - Select a file with `<M>`, the file when selected will have a `*` prepended to its name
+  - Select all files in the current directory with `<CTRL+A>`
+  - Read more on manual: [Work on multiple files](docs/man.md#Work-on-multiple-files-)
+- **Logging**:
+  - termscp now writes a log file, useful to debug and to contribute to fix issues.
+  - Read more on [manual](docs/man.md)
+- **File transfer changes**
+  - *SFTP*
+    - Added **COPY** command to SFTP (Please note that Copy command is not supported by SFTP natively, so here it just uses the `cp` shell command as it does in SCP).
+  - *FTP*
+    - Added support for file copy (achieved through *tricky-copy*: the file is first downloaded, then uploaded with a different file name)
+- **Double progress bar**:
+  - From now one two progress bar will be displayed:
+    - the first, on top, displays the full transfer state (e.g. when downloading a directory of 10 files, the progress of the entire transfer)
+    - the second, on bottom, displays the transfer of the individual file being written (as happened for the old versions)
+    - changed the progress bar colour from `LightGreen` to `Green`
+- Enhancements
+  - Added a status bar in the file explorer showing whether the sync browser is enabled and which file sorting mode is selected
+  - Removed the goold old figlet title
+  - Protocol input as first field in UI
+  - Port is now updated to standard for selected protocol
+    - when you change the protocol in the authentication form and the current port is standard (`< 1024`), the port will be automatically changed to default value for the selected protocol (e.g. current port: `123`, protocol changed to `FTP`, port becomes `21`)
+- Bugfix:
+  - Fixed wrong text wrap in log box
+  - Fixed empty bookmark name causing termscp to crash
+  - Fixed error message not being shown after an upload failure
+  - Fixed default protocol not being loaded from config
+  - [Issue 23](https://github.com/veeso/termscp/issues/23): Remove created file if transfer failed or was abrupted
+- Dependencies:
+  - Added `tui-realm 0.3.0`
+  - Removed `tui` (as direct dependency)
+  - Updated `regex` to `1.5.4`

+## 0.4.2
+
+Released on 13/04/2021
+

+- Bugfix:
+  - removed `eprintln!` in ftp transfer causing UI to break in Windows
+
+## 0.4.1
+
+Released on 07/04/2021
+
+- Enhancements:
+  - SCP file transfer:
+    - Added possibility to stat directories.

+  - [Issue 17](https://github.com/veeso/termscp/issues/17)
+    - SCP: fixed symlink not properly detected
+    - FTP: added symlink support for Linux targets
+  - [Issue 10](https://github.com/veeso/termscp/issues/10): Fixed port not being loaded from bookmarks into gui
+  - [Issue 9](https://github.com/veeso/termscp/issues/9): Fixed issues related to paths on remote when using Windows
+- Dependencies:
+  - Added `path-slash 0.1.4` (Windows only)
+  - Added `thiserror 1.0.24`
+  - Updated `edit` to `0.1.3`
+  - Updated `magic-crypt` to `3.1.7`

+
+## 0.4.0
+
+Released on 27/03/2021
+
+> The UI refactoring update
+
+- **New explorer features**:
+  - **Execute** a command pressing `X`. This feature is supported on both local and remote hosts (only SFTP/SCP protocols support this feature).
+  - **Find**: search for files pressing `F` using wild matches.
+- Enhancements:
+  - Input fields will now support **"input keys"** (such as moving cursor, DEL, END, HOME, ...)
+  - Improved performance regarding configuration I/O (config client is now shared in the activity context)
+  - Fetch latest version from Github once; cache previous value in the Context Storage.
+- Bugfix:
+  - Prevent resetting explorer index on remote tab after performing certain actions (list dir, exec, ...)
+  - SCP file transfer: prevent infinite loops while performing `stat` on symbolic links pointing to themselves (e.g. `mylink -> mylink`)
+  - Fixed a bug causing termscp to crash if removing a bookmark
+  - Fixed file format cursor position in the GUI
+  - Fixed a bug causing termscp to show two equal bookmarks when overwriting one.
+  - Fixed system tests which deleted the termscp configuration when launched
+- **LICENSE**: changed license to MIT
+- Dependencies:
+  - Removed `unicode-width`
+  - Added `wildmatch 1.0.13`
+- For developers:
+  - Activity refactoring
+    - Developed an internal library used to create components, components are then nested inside a View
+    - The new engine works through properties and states, then returns Messages. I was inspired by both React and Elm.
+
+## 0.3.3
+
+Released on 28/02/2021
+
+- **Format key attributes**:
+  - Added `EXTRA` and `LENGTH` parameters to format keys.
+  - Now keys are provided with this syntax `{KEY_NAME[:LEN[:EXTRA]}`
+- **Check for updates**:
+  - termscp will now check for updates on startup and will show in the main page if there is a new version available
+  - This feature may be disabled from setup (Check for updates => No)
+- Enhancements:
+  - Default choice for deleting file set to "NO" (way too easy to delete files by mistake)
+  - Added CLI options to set starting workind directory on both local and remote hosts
+  - Parse remote host now uses a Regex to gather parts (increased stability).
+  - Now bookmarks and recents are sorted in the UI (bookmarks are sorted by name; recents are sorted by connection datetime)
+  - Improved stability
+
+## 0.3.2
+
+Released on 24/01/2021
+
+- **Explorer Formatter**:
+  - Added possibility to customize the format when listing files in the explorers (Read more on README)
+  - Added `file_fmt` key to configuration (if missing, default will be used).
+  - Added the text input to the Settings view to set the value for `file_fmt`.
+- Bugfix:
+  - Solved file index in explorer files at start of termscp, in case the first entry is an hidden file
+  - SCP File transfer: when listing directory entries, check if a symlink points to a directory or to a file
+- Dependencies:
+  - updated `crossterm` to `0.19.0`
+  - updated `rand` to `0.8.2`
+  - updated `rpassword` to `5.0.1`
+  - updated `serde` to `1.0.121`
+  - updated `tui` to `0.14.0`
+  - updated `whoami` to `1.1.0`
+
+## 0.3.1
+
+Released on 18/01/2021
+
+- **Keyring to store secrets**
+  - On both MacOS and Windows, the secret used to encrypt passwords in bookmarks it is now store in the OS secret vault. This provides much more security to store the password
+- Enhancements:
+  - Added connection timeout to 30 seconds to SFTP/SCP clients and improved name lookup system.
+- Bugfix:
+  - Solved index in explorer files list which was no more kept after 0.3.0
+  - SCP file transfer: fixed possible wrong file size when sending file, due to a possible incoherent size between the file explorer and the actual file size.
+- Breaking changes: on **MacOS / Windows systems only**, the password you saved for bookmarks won't be working anymore if you have support for the keyring crate. Because of the migration to keyring, the previously used secret hasn't been migrated to the storage, instead a new secret will be used. To solve this, just save the bookmark again with the password.
+
+## 0.3.0
+
+ Released on 10/01/2021
+
+> The SSH Key Storage Update
+
+- **SSH Key Storage**

+
+## Project mission
+
+termscp was born because, as a terminal lover and Linux user, I wanted something like WinSCP on Linux and on terminal. I my previous job I used SFTP/SCP pratically everyday and that made me to desire an application like termscp so much, that eventually I started to work on it in the spare time. I saw there was a very cool library to create terminal user interface (`tui-rs`), so I started to code it. I wrote termscp as an experiment, I designed kinda nothing at the time. I just said
+
+> Ok, there must be a `FileTransfer` trait somehow, I'll have more views, so I'll use something like Android activities, and there must be a module to interact with the local host".
+
+And so in december 2020 I had the first version of termscp running and it worked, but was very simple, raw and minimal.
+A lot of things have changed since them, both the features the project provides and my personal view of this project.
+
+Today I don't see termscp as a WinSCP clone anymore. I've also thought about changing the name as the time passed by, but I liked it and it would be hard to change the name on the registries, etc.
+
+Right now I see termscp as a **rich-featured file transfer client for terminals**. All I want is to provide all the features users need to use it correctly, I want it to be **safe and reliable** and eventually I want people to consider termscp **the first choice as a file transfer client**.
+
+### Project goals
+
+- Have support for all the most used file transfer protocol
+- Provide all the features a file explorer requires
+- Have a well designed application
+- Make a reliable, safe and fast application
+
+---
+
+## Open an issue
+
+Open an issue when:
+
+- You have questions or concerns regarding the project or the application itself.
+- You have a bug to report.
+- You have a feature or a suggestion to improve termscp to submit.
+
+### Questions
+
+If you have a question open an issue using the `Question` template.
+By default your question should already be labeled with the `question` label, if you need help with your installation, please also add the `help wanted` label.
+Check the issue is always assigned to `veeso`.
+
+### Bug reports
+
+If you want to report an issue or a bug you've encountered while using termscp, open an issue using the `Bug report` template.
+The `Bug` label should already be set and the issue should already be assigned to `veeso`.
+Don't set other labels to your issue, not even priority.
+
+When you open a bug try to be the most precise as possible in describing your issue. I'm not saying you should always be that precise, since sometimes it's very easy for maintainers to understand what you're talking about. Just try to be reasonable to understand sometimes we might not know what you're talking about or we just don't have the technical knowledge you might think.
+Please always provide the environment you're working on and consider that we don't provide any support for older version of termscp, at least for those not classified as LTS (if we'll ever have them).
+If you can, provide the log file or the snippet involving your issue. You can find in the [user manual](docs/man.md) the location of the log file.
+Last but not least: the template I've written must be used. Full stop.
+
+Maintainers will may add additional labels to your issue:
+
+- **duplicate**: the issue is duplicated; the reference to the related issue will be added to your description. Your issue will be closed.
+- **priority**: this must be fixed asap
+- **sorcery**: it is not possible to find out what's causing your bug, nor is reproducible on our test environments.
+- **wontfix**: your bug has a very high ratio between the difficulty to fix it and the probability to encounter it, or it just isn't a bug, but a feature.
+
+### Feature requests
+
+Whenever you have a good idea which chould improve the project, it is a good idea to submit it to the project owner.
+The first thing you should do though, is not starting to write the code, but is to become concern about how termscp works, what kind
+of contribution I appreciate and what kind of contribution I won't consider.
+Said so, follow these steps:
+
+- Read the contributing guidelines, entirely
+- Think on whether your idea would fit in the project mission and guidelines or not
+- Think about the impact your idea would have on the project
+- Open an issue using the `feature request` template describing with accuracy your suggestion
+- Wait for the maintainer feedback on your idea
+
+If you want to implement the feature by yourself and your suggestion gets approved, start writing the code. Remember that on [docs.rs](https://docs.rs/termscp) there is the documentation for the project. Open a PR related to your issue. See [Pull request process for more details](#pull-request-process)
+
+It is very important to follow these steps, since it will prevent you from working on a feature that will be rejected and trust me, none of us wants to deal with this situation.
+
+Always mind that your suggestion, may be rejected: I'll always provide a feedback on the reasons that brought me to reject your feature, just try not to get mad about that.

 ## Pull Request Process
 
 Let's make it simple and clear:
 
-1. Open an issue with an **appropriate label** (e.g. bug, enhancement, ...).
-2. Write a **properly documentation** compliant with **rustdoc** standard.
-3. Write tests for your code. This doesn't apply necessarily for implementation regarding the user-interface module (`ui`).
-4. Report changes to the issue you opened, writing a report of what you changed and what you have introduced.
-5. Update the `CHANGELOG.md` file with details of changes to the application.
-6. Request maintainers to merge your changes.
+1. Open a PR with an **appropriate label** (e.g. bug, enhancement, ...).
+2. Write a **properly documentation** for your software compliant with **rustdoc** standard.
+3. Write tests for your code. This doesn't apply necessarily for implementation regarding the user-interface module (`ui/activities`) and (if a test server is not available) for file transfers.
+4. Check your code with `cargo clippy`.
+5. Check if the CI for your commits reports three-green.
+6. Report changes to the PR you opened, writing a report of what you changed and what you have introduced.
+7. Update the `CHANGELOG.md` file with details of changes to the application. In changelog report changes under a chapter called `PR{PULL_REQUEST_NUMBER}` (e.g. PR12).
+8. Assign a maintainer to the reviewers.
+9. Request maintainers to merge your changes.
+
+### Software guidelines
+
+In addition to the process described for the PRs, I've also decided to introduce a list of guidelines to follow when writing the code, that should be followed:
+
+1. **Let's stop the NPM apocalypse**: personally I'm against the abuse of dependencies we make in software projects and I think that NodeJS has opened the way to this drama (and has already gone too far). Nowadays nobody cares about adding hundreds of dependencies to their projects. Don't misunderstand me: I think that package managers are cool, but I'm totally against the abuse we're making of them. I think when we work on a project, we should try to use the minor quantity of dependencies as possible, especially because it's not hard to see how many libraries are getting abandoned right now, causing compatibility issues after a while. So please, when working on termscp, try not to add useless dependencies.
+2. **No C-bindings**: personally I think that Rust still relies too much on C. And that's bad, really bad. Many libraries in Rust are just wrappers to C libraries, which is a huge problem, especially considering this is a multiplatform project. Everytime you add a C-binding to your project, you're forcing your users to install additional libraries to their systems. Sometimes these libraries are already installed on their systems (as happens for libssh2 or openssl in this case), but sometimes not. So if you really have to add a dependency to this project, please AVOID completely adding C-bounded libraries.
+3. **Test units matter**: Whenever you implement something new to this project, always implement test units which cover the most cases as possible.
+4. **Comments are useful**: Many people say that the code should be that simple to talk by itself about what it does, and comments should then be useless. I personally don't agree. I'm not saying they're wrong, but I'm just saying that this approach has, in my personal opinion, many aspects which are underrated:
+   1. What's obvious for me, might not be for the others.
+   2. Our capacity to work on a code depends mostly on **time and experience**, not on complexity: I'm not denying complexity matter, but the most decisive factor when working on code is the experience we've acquired working on it and the time we've spent. As the author of the project, I know the project like the back of my hands, but if I didn't work on it for a year, then I would probably have some problems in working on it again as the same speed as before. And do you know what's really time-saving in these cases? Comments.
 
 ## Developer contributions guide
 
-Welcome to the contributions guide for TermSCP. This chapter DOESN'T contain the documentation for TermSCP, which can instead be found on Rust Docs at <https://docs.rs/termscp>
-This chapter describes how TermSCP works and the guide lines to implement stuff such as file transfers and add features to the user interface.
-
-### How TermSCP works
-
-TermSCP is basically made up of 4 components:
-
-- the **filetransfer**: the filetransfer takes care of managing the remote file system; it provides function to establish a connection with the remote, operating on the remote server file system (e.g. remove files, make directories, rename files, ...), read files and write files. The FileTransfer, as we'll see later, is actually a trait, and for each protocol a FileTransfer must be implement the trait.
-- the **host**: the host module provides functions to interact with the local host file system.
-- the **ui**: this module contains the implementation of the user interface, as we'll see in the next chapter, this is achieved through **activities**.
-- the **activity_manager**: the activity manager takes care of managing activities, basically it runs the activities of the user interface, and chooses, based on their state, when is the moment to terminate the current activity and which activity to run after the current one.
-
-#### Activities
-
-Just a little paragraph about activities. Really, read the code and the documentation to have a clear idea of how the ui works.
-I think there are many ways to implement a user interface; for termscp, I decided to go for a **Android-like** approach.
-Android works with Activity, each activity represents a view and there is a context shared between them, and so it works here.
-
-Just a little note about activities, activities work with a `Context`, the context is a data holder for different data, which are shared and common between the activities.
-
-I've implemented a Trait called `Activity`, which, is a very very reduced version of the Android activity of course.
-This trait provides only 3 methods:
-
-- `on_create`: this method must initialize the activity; the context is passed to the activity, which will be the only owner of the Context, until the activity terminates.
-- `on_draw`: this method must be called each time you want to perform an update of the user interface. This is basically the run method of the activity. This method also cares about handling input events. The developer shouldn't draw the interface on each call of this method (consider that this method might be called hundreds of times per second), but only when actually something has changed (for example after an input event has been raised).
-- `on_destroy`: this method finalizes the activity and drops it; this method returns the Context to the caller (the activity manager).

-### Implementing File Transfers
-
-This chapter describes how to implement a file transfer in TermSCP. A file transfer is a module which implements the `FileTransfer` trait. The file transfer provides different modules to interact with a remote server, which in addition to the most obvious methods, used to download and upload files, provides also methods to list files, delete files, create directories etc.
-
-In the following steps I will describe how to implement a new file transfer, in this case I will be implementing the SCP file transfer (which I'm actually implementing the moment I'm writing this lines).
-
-1. Add the Scp protocol to the `FileTransferProtocol` enum.
-
-    Move to `src/filetransfer/mod.rs` and add `Scp` to the `FileTransferProtocol` enum
-
-    ```rs
-    /// ## FileTransferProtocol
-    ///
-    /// This enum defines the different transfer protocol available in TermSCP
-    #[derive(std::cmp::PartialEq, std::fmt::Debug, std::clone::Clone)]
-    pub enum FileTransferProtocol {
-        Sftp,
-        Ftp(bool), // Bool is for secure (true => ftps)
-        Scp, // <-- here
-    }
-    ```
-
-    In this case Scp is a "plain" enum type. If you need particular options, follow the implementation of `Ftp` which uses a boolean flag for indicating if using FTPS or FTP.
-
-2. Implement the FileTransfer struct
-
-    Create a file at `src/filetransfer/mytransfer.rs`
-
-    Declare your file transfer struct
-
-    ```rs
-    /// ## ScpFileTransfer
-    ///
-    /// SFTP file transfer structure
-    pub struct ScpFileTransfer {
-        session: Option<Session>,
-        sftp: Option<Sftp>,
-        wrkdir: PathBuf,
-    }
-    ```
-
-3. Implement the `FileTransfer` trait for it
-
-    You'll have to implement the following methods for your file transfer:
-
-    - connect: connect to remote server
-    - disconnect: disconnect from remote server
-    - is_connected: returns whether the file transfer is connected to remote
-    - pwd: get working directory
-    - change_dir: change working directory.
-    - list_dir: get files and directories at a certain path
-    - mkdir: make a new directory. Return an error in case the directory already exists
-    - remove: remove a file or a directory. In case the protocol doesn't support recursive removing of directories you MUST implement this through a recursive algorithm
-    - rename: rename a file or a directory
-    - stat: returns detail for a certain path
-    - send_file: opens a stream to a remote path for write purposes (write a remote file)
-    - recv_file: opens a stream to a remote path for read purposes (write a local file)
-    - on_sent: finalize a stream when writing a remote file. In case it's not necessary just return `Ok(())`
-    - on_recv: fianlize a stream when reading a remote file. In case it's not necessary just return `Ok(())`
-
-    In case the protocol you're working on doesn't support any of this features, just return `Err(FileTransferError::new(FileTransferErrorType::UnsupportedFeature))`
-
-4. Add your transfer to filetransfers:
-
-    Move to `src/filetransfer/mod.rs` and declare your file transfer:
-
-    ```rs
-    // Transfers
-    pub mod ftp_transfer;
-    pub mod scp_transfer; // <-- here
-    pub mod sftp_transfer;
-    ```
-
-5. Handle FileTransfer in `FileTransferActivity::new`
-
-    Move to `src/ui/activities/filetransfer_activity/mod.rs` and add the new protocol to the client match
-
-    ```rs
-    client: match protocol {
-        FileTransferProtocol::Sftp => Box::new(SftpFileTransfer::new()),
-        FileTransferProtocol::Ftp(ftps) => Box::new(FtpFileTransfer::new(ftps)),
-        FileTransferProtocol::Scp => Box::new(ScpFileTransfer::new()), // <--- here
-    },
-    ```
-
-6. Handle right/left input events in `AuthActivity`:
-
-    Move to `src/ui/activities/auth_activity.rs` and handle the new protocol in `handle_input_event_mode_text` for `KeyCode::Left` and `KeyCode::Right`.
-    Consider that the order they "rotate" must match the way they will be drawned in the interface.
-    For newer protocols, please put them always at the end of the list. In this list I won't, because Scp is more important than Ftp imo.
-
-    ```rs
-    KeyCode::Left => {
-        // If current field is Protocol handle event... (move element left)
-        if self.selected_field == InputField::Protocol {
-            self.protocol = match self.protocol {
-                FileTransferProtocol::Sftp => FileTransferProtocol::Ftp(true), // End of list (wrap)
-                FileTransferProtocol::Scp => FileTransferProtocol::Sftp,
-                FileTransferProtocol::Ftp(ftps) => match ftps {
-                    false => FileTransferProtocol::Scp,
-                    true => FileTransferProtocol::Ftp(false),
-                }
-            };
-        }
-    }
-    KeyCode::Right => {
-        // If current field is Protocol handle event... ( move element right )
-        if self.selected_field == InputField::Protocol {
-            self.protocol = match self.protocol {
-                FileTransferProtocol::Sftp => FileTransferProtocol::Scp,
-                FileTransferProtocol::Scp => FileTransferProtocol::Ftp(false),
-                FileTransferProtocol::Ftp(ftps) => match ftps {
-                    false => FileTransferProtocol::Ftp(true),
-                    true => FileTransferProtocol::Sftp, // End of list (wrap)
-                }
-            };
-        }
-    }
-    ```
-
-7. Add your new file transfer to the protocol input field
-
-    Move to `AuthActivity::draw_protocol_select` method.
-    Here add your new protocol to the `Spans` vector and to the match case, which chooses which element to highlight.
-
-    ```rs
-    let protocols: Vec<Spans> = vec![Spans::from("SFTP"), Spans::from("SCP"), Spans::from("FTP"), Spans::from("FTPS")];
-    let index: usize = match self.protocol {
-        FileTransferProtocol::Sftp => 0,
-        FileTransferProtocol::Scp => 1,
-        FileTransferProtocol::Ftp(ftps) => match ftps {
-            false => 2,
-            true => 3,
-        }
-    };
-    ```

- of this license document, but changing it is not allowed.
-
-                            Preamble
-
-  The GNU General Public License is a free, copyleft license for
-software and other kinds of works.
-
-  The licenses for most software and other practical works are designed
-to take away your freedom to share and change the works.  By contrast,
-the GNU General Public License is intended to guarantee your freedom to
-share and change all versions of a program--to make sure it remains free
-software for all its users.  We, the Free Software Foundation, use the
-GNU General Public License for most of our software; it applies also to
-any other work released this way by its authors.  You can apply it to
-your programs, too.
-
-  When we speak of free software, we are referring to freedom, not
-price.  Our General Public Licenses are designed to make sure that you
-have the freedom to distribute copies of free software (and charge for
-them if you wish), that you receive source code or can get it if you
-want it, that you can change the software or use pieces of it in new
-free programs, and that you know you can do these things.
-
-  To protect your rights, we need to prevent others from denying you
-these rights or asking you to surrender the rights.  Therefore, you have
-certain responsibilities if you distribute copies of the software, or if
-you modify it: responsibilities to respect the freedom of others.
-
-  For example, if you distribute copies of such a program, whether
-gratis or for a fee, you must pass on to the recipients the same
-freedoms that you received.  You must make sure that they, too, receive
-or can get the source code.  And you must show them these terms so they
-know their rights.
-
-  Developers that use the GNU GPL protect your rights with two steps:
-(1) assert copyright on the software, and (2) offer you this License
-giving you legal permission to copy, distribute and/or modify it.
-
-  For the developers' and authors' protection, the GPL clearly explains
-that there is no warranty for this free software.  For both users' and
-authors' sake, the GPL requires that modified versions be marked as
-changed, so that their problems will not be attributed erroneously to
-authors of previous versions.
-
-  Some devices are designed to deny users access to install or run
-modified versions of the software inside them, although the manufacturer
-can do so.  This is fundamentally incompatible with the aim of
-protecting users' freedom to change the software.  The systematic
-pattern of such abuse occurs in the area of products for individuals to
-use, which is precisely where it is most unacceptable.  Therefore, we
-have designed this version of the GPL to prohibit the practice for those
-products.  If such problems arise substantially in other domains, we
-stand ready to extend this provision to those domains in future versions
-of the GPL, as needed to protect the freedom of users.
-
-  Finally, every program is threatened constantly by software patents.
-States should not allow patents to restrict development and use of
-software on general-purpose computers, but in those that do, we wish to
-avoid the special danger that patents applied to a free program could
-make it effectively proprietary.  To prevent this, the GPL assures that
-patents cannot be used to render the program non-free.
-
-  The precise terms and conditions for copying, distribution and
-modification follow.
-
-                       TERMS AND CONDITIONS
-
-  0. Definitions.
-
-  "This License" refers to version 3 of the GNU General Public License.
-
-  "Copyright" also means copyright-like laws that apply to other kinds of
-works, such as semiconductor masks.
-
-  "The Program" refers to any copyrightable work licensed under this
-License.  Each licensee is addressed as "you".  "Licensees" and
-"recipients" may be individuals or organizations.
-
-  To "modify" a work means to copy from or adapt all or part of the work
-in a fashion requiring copyright permission, other than the making of an
-exact copy.  The resulting work is called a "modified version" of the
-earlier work or a work "based on" the earlier work.
-
-  A "covered work" means either the unmodified Program or a work based
-on the Program.
-
-  To "propagate" a work means to do anything with it that, without
-permission, would make you directly or secondarily liable for
-infringement under applicable copyright law, except executing it on a
-computer or modifying a private copy.  Propagation includes copying,
-distribution (with or without modification), making available to the
-public, and in some countries other activities as well.
-
-  To "convey" a work means any kind of propagation that enables other
-parties to make or receive copies.  Mere interaction with a user through
-a computer network, with no transfer of a copy, is not conveying.
-
-  An interactive user interface displays "Appropriate Legal Notices"
-to the extent that it includes a convenient and prominently visible
-feature that (1) displays an appropriate copyright notice, and (2)
-tells the user that there is no warranty for the work (except to the
-extent that warranties are provided), that licensees may convey the
-work under this License, and how to view a copy of this License.  If
-the interface presents a list of user commands or options, such as a
-menu, a prominent item in the list meets this criterion.
-
-  1. Source Code.
-
-  The "source code" for a work means the preferred form of the work
-for making modifications to it.  "Object code" means any non-source
-form of a work.
-
-  A "Standard Interface" means an interface that either is an official
-standard defined by a recognized standards body, or, in the case of
-interfaces specified for a particular programming language, one that
-is widely used among developers working in that language.
-
-  The "System Libraries" of an executable work include anything, other
-than the work as a whole, that (a) is included in the normal form of
-packaging a Major Component, but which is not part of that Major
-Component, and (b) serves only to enable use of the work with that
-Major Component, or to implement a Standard Interface for which an
-implementation is available to the public in source code form.  A
-"Major Component", in this context, means a major essential component
-(kernel, window system, and so on) of the specific operating system
-(if any) on which the executable work runs, or a compiler used to
-produce the work, or an object code interpreter used to run it.
-
-  The "Corresponding Source" for a work in object code form means all
-the source code needed to generate, install, and (for an executable
-work) run the object code and to modify the work, including scripts to
-control those activities.  However, it does not include the work's
-System Libraries, or general-purpose tools or generally available free
-programs which are used unmodified in performing those activities but
-which are not part of the work.  For example, Corresponding Source
-includes interface definition files associated with source files for
-the work, and the source code for shared libraries and dynamically
-linked subprograms that the work is specifically designed to require,
-such as by intimate data communication or control flow between those
-subprograms and other parts of the work.
-
-  The Corresponding Source need not include anything that users
-can regenerate automatically from other parts of the Corresponding
-Source.
-
-  The Corresponding Source for a work in source code form is that
-same work.
-
-  2. Basic Permissions.
-
-  All rights granted under this License are granted for the term of
-copyright on the Program, and are irrevocable provided the stated
-conditions are met.  This License explicitly affirms your unlimited
-permission to run the unmodified Program.  The output from running a
-covered work is covered by this License only if the output, given its
-content, constitutes a covered work.  This License acknowledges your
-rights of fair use or other equivalent, as provided by copyright law.
-
-  You may make, run and propagate covered works that you do not
-convey, without conditions so long as your license otherwise remains
-in force.  You may convey covered works to others for the sole purpose
-of having them make modifications exclusively for you, or provide you
-with facilities for running those works, provided that you comply with
-the terms of this License in conveying all material for which you do
-not control copyright.  Those thus making or running the covered works
-for you must do so exclusively on your behalf, under your direction
-and control, on terms that prohibit them from making any copies of
-your copyrighted material outside their relationship with you.
-
-  Conveying under any other circumstances is permitted solely under
-the conditions stated below.  Sublicensing is not allowed; section 10
-makes it unnecessary.
-
-  3. Protecting Users' Legal Rights From Anti-Circumvention Law.
-
-  No covered work shall be deemed part of an effective technological
-measure under any applicable law fulfilling obligations under article
-11 of the WIPO copyright treaty adopted on 20 December 1996, or
-similar laws prohibiting or restricting circumvention of such
-measures.
-
-  When you convey a covered work, you waive any legal power to forbid
-circumvention of technological measures to the extent such circumvention
-is effected by exercising rights under this License with respect to
-the covered work, and you disclaim any intention to limit operation or
-modification of the work as a means of enforcing, against the work's
-users, your or third parties' legal rights to forbid circumvention of
-technological measures.
-
-  4. Conveying Verbatim Copies.
-
-  You may convey verbatim copies of the Program's source code as you
-receive it, in any medium, provided that you conspicuously and
-appropriately publish on each copy an appropriate copyright notice;
-keep intact all notices stating that this License and any
-non-permissive terms added in accord with section 7 apply to the code;
-keep intact all notices of the absence of any warranty; and give all
-recipients a copy of this License along with the Program.
-
-  You may charge any price or no price for each copy that you convey,
-and you may offer support or warranty protection for a fee.
-
-  5. Conveying Modified Source Versions.
-
-  You may convey a work based on the Program, or the modifications to
-produce it from the Program, in the form of source code under the
-terms of section 4, provided that you also meet all of these conditions:
-
-    a) The work must carry prominent notices stating that you modified
-    it, and giving a relevant date.
-
-    b) The work must carry prominent notices stating that it is
-    released under this License and any conditions added under section
-    7.  This requirement modifies the requirement in section 4 to
-    "keep intact all notices".
-
-    c) You must license the entire work, as a whole, under this
-    License to anyone who comes into possession of a copy.  This
-    License will therefore apply, along with any applicable section 7
-    additional terms, to the whole of the work, and all its parts,
-    regardless of how they are packaged.  This License gives no
-    permission to license the work in any other way, but it does not
-    invalidate such permission if you have separately received it.
-
-    d) If the work has interactive user interfaces, each must display
-    Appropriate Legal Notices; however, if the Program has interactive
-    interfaces that do not display Appropriate Legal Notices, your
-    work need not make them do so.
-
-  A compilation of a covered work with other separate and independent
-works, which are not by their nature extensions of the covered work,
-and which are not combined with it such as to form a larger program,
-in or on a volume of a storage or distribution medium, is called an
-"aggregate" if the compilation and its resulting copyright are not
-used to limit the access or legal rights of the compilation's users
-beyond what the individual works permit.  Inclusion of a covered work
-in an aggregate does not cause this License to apply to the other
-parts of the aggregate.
-
-  6. Conveying Non-Source Forms.
-
-  You may convey a covered work in object code form under the terms
-of sections 4 and 5, provided that you also convey the
-machine-readable Corresponding Source under the terms of this License,
-in one of these ways:
-
-    a) Convey the object code in, or embodied in, a physical product
-    (including a physical distribution medium), accompanied by the
-    Corresponding Source fixed on a durable physical medium
-    customarily used for software interchange.
-
-    b) Convey the object code in, or embodied in, a physical product
-    (including a physical distribution medium), accompanied by a
-    written offer, valid for at least three years and valid for as
-    long as you offer spare parts or customer support for that product
-    model, to give anyone who possesses the object code either (1) a
-    copy of the Corresponding Source for all the software in the
-    product that is covered by this License, on a durable physical
-    medium customarily used for software interchange, for a price no
-    more than your reasonable cost of physically performing this
-    conveying of source, or (2) access to copy the
-    Corresponding Source from a network server at no charge.
-
-    c) Convey individual copies of the object code with a copy of the
-    written offer to provide the Corresponding Source.  This
-    alternative is allowed only occasionally and noncommercially, and
-    only if you received the object code with such an offer, in accord
-    with subsection 6b.
-
-    d) Convey the object code by offering access from a designated
-    place (gratis or for a charge), and offer equivalent access to the
-    Corresponding Source in the same way through the same place at no
-    further charge.  You need not require recipients to copy the
-    Corresponding Source along with the object code.  If the place to
-    copy the object code is a network server, the Corresponding Source
-    may be on a different server (operated by you or a third party)
-    that supports equivalent copying facilities, provided you maintain
-    clear directions next to the object code saying where to find the
-    Corresponding Source.  Regardless of what server hosts the
-    Corresponding Source, you remain obligated to ensure that it is
-    available for as long as needed to satisfy these requirements.
-
-    e) Convey the object code using peer-to-peer transmission, provided
-    you inform other peers where the object code and Corresponding
-    Source of the work are being offered to the general public at no
-    charge under subsection 6d.
-
-  A separable portion of the object code, whose source code is excluded
-from the Corresponding Source as a System Library, need not be
-included in conveying the object code work.
-
-  A "User Product" is either (1) a "consumer product", which means any
-tangible personal property which is normally used for personal, family,
-or household purposes, or (2) anything designed or sold for incorporation
-into a dwelling.  In determining whether a product is a consumer product,
-doubtful cases shall be resolved in favor of coverage.  For a particular
-product received by a particular user, "normally used" refers to a
-typical or common use of that class of product, regardless of the status
-of the particular user or of the way in which the particular user
-actually uses, or expects or is expected to use, the product.  A product
-is a consumer product regardless of whether the product has substantial
-commercial, industrial or non-consumer uses, unless such uses represent
-the only significant mode of use of the product.
-
-  "Installation Information" for a User Product means any methods,
-procedures, authorization keys, or other information required to install
-and execute modified versions of a covered work in that User Product from
-a modified version of its Corresponding Source.  The information must
-suffice to ensure that the continued functioning of the modified object
-code is in no case prevented or interfered with solely because
-modification has been made.
-
-  If you convey an object code work under this section in, or with, or
-specifically for use in, a User Product, and the conveying occurs as
-part of a transaction in which the right of possession and use of the
-User Product is transferred to the recipient in perpetuity or for a
-fixed term (regardless of how the transaction is characterized), the
-Corresponding Source conveyed under this section must be accompanied
-by the Installation Information.  But this requirement does not apply
-if neither you nor any third party retains the ability to install
-modified object code on the User Product (for example, the work has
-been installed in ROM).
-
-  The requirement to provide Installation Information does not include a
-requirement to continue to provide support service, warranty, or updates
-for a work that has been modified or installed by the recipient, or for
-the User Product in which it has been modified or installed.  Access to a
-network may be denied when the modification itself materially and
-adversely affects the operation of the network or violates the rules and
-protocols for communication across the network.
-
-  Corresponding Source conveyed, and Installation Information provided,
-in accord with this section must be in a format that is publicly
-documented (and with an implementation available to the public in
-source code form), and must require no special password or key for
-unpacking, reading or copying.
-
-  7. Additional Terms.
-
-  "Additional permissions" are terms that supplement the terms of this
-License by making exceptions from one or more of its conditions.
-Additional permissions that are applicable to the entire Program shall
-be treated as though they were included in this License, to the extent
-that they are valid under applicable law.  If additional permissions
-apply only to part of the Program, that part may be used separately
-under those permissions, but the entire Program remains governed by
-this License without regard to the additional permissions.
-
-  When you convey a copy of a covered work, you may at your option
-remove any additional permissions from that copy, or from any part of
-it.  (Additional permissions may be written to require their own
-removal in certain cases when you modify the work.)  You may place
-additional permissions on material, added by you to a covered work,
-for which you have or can give appropriate copyright permission.
-
-  Notwithstanding any other provision of this License, for material you
-add to a covered work, you may (if authorized by the copyright holders of
-that material) supplement the terms of this License with terms:
-
-    a) Disclaiming warranty or limiting liability differently from the
-    terms of sections 15 and 16 of this License; or
-
-    b) Requiring preservation of specified reasonable legal notices or
-    author attributions in that material or in the Appropriate Legal
-    Notices displayed by works containing it; or
-
-    c) Prohibiting misrepresentation of the origin of that material, or
-    requiring that modified versions of such material be marked in
-    reasonable ways as different from the original version; or
-
-    d) Limiting the use for publicity purposes of names of licensors or
-    authors of the material; or
-
-    e) Declining to grant rights under trademark law for use of some
-    trade names, trademarks, or service marks; or
-
-    f) Requiring indemnification of licensors and authors of that
-    material by anyone who conveys the material (or modified versions of
-    it) with contractual assumptions of liability to the recipient, for
-    any liability that these contractual assumptions directly impose on
-    those licensors and authors.
-
-  All other non-permissive additional terms are considered "further
-restrictions" within the meaning of section 10.  If the Program as you
-received it, or any part of it, contains a notice stating that it is
-governed by this License along with a term that is a further
-restriction, you may remove that term.  If a license document contains
-a further restriction but permits relicensing or conveying under this
-License, you may add to a covered work material governed by the terms
-of that license document, provided that the further restriction does
-not survive such relicensing or conveying.
-
-  If you add terms to a covered work in accord with this section, you
-must place, in the relevant source files, a statement of the
-additional terms that apply to those files, or a notice indicating
-where to find the applicable terms.
-
-  Additional terms, permissive or non-permissive, may be stated in the
-form of a separately written license, or stated as exceptions;
-the above requirements apply either way.
-
-  8. Termination.
-
-  You may not propagate or modify a covered work except as expressly
-provided under this License.  Any attempt otherwise to propagate or
-modify it is void, and will automatically terminate your rights under
-this License (including any patent licenses granted under the third
-paragraph of section 11).
-
-  However, if you cease all violation of this License, then your
-license from a particular copyright holder is reinstated (a)
-provisionally, unless and until the copyright holder explicitly and
-finally terminates your license, and (b) permanently, if the copyright
-holder fails to notify you of the violation by some reasonable means
-prior to 60 days after the cessation.
-
-  Moreover, your license from a particular copyright holder is
-reinstated permanently if the copyright holder notifies you of the
-violation by some reasonable means, this is the first time you have
-received notice of violation of this License (for any work) from that
-copyright holder, and you cure the violation prior to 30 days after
-your receipt of the notice.
-
-  Termination of your rights under this section does not terminate the
-licenses of parties who have received copies or rights from you under
-this License.  If your rights have been terminated and not permanently
-reinstated, you do not qualify to receive new licenses for the same
-material under section 10.
-
-  9. Acceptance Not Required for Having Copies.
-
-  You are not required to accept this License in order to receive or
-run a copy of the Program.  Ancillary propagation of a covered work
-occurring solely as a consequence of using peer-to-peer transmission
-to receive a copy likewise does not require acceptance.  However,
-nothing other than this License grants you permission to propagate or
-modify any covered work.  These actions infringe copyright if you do
-not accept this License.  Therefore, by modifying or propagating a
-covered work, you indicate your acceptance of this License to do so.
-
-  10. Automatic Licensing of Downstream Recipients.
-
-  Each time you convey a covered work, the recipient automatically
-receives a license from the original licensors, to run, modify and
-propagate that work, subject to this License.  You are not responsible
-for enforcing compliance by third parties with this License.
-
-  An "entity transaction" is a transaction transferring control of an
-organization, or substantially all assets of one, or subdividing an
-organization, or merging organizations.  If propagation of a covered
-work results from an entity transaction, each party to that
-transaction who receives a copy of the work also receives whatever
-licenses to the work the party's predecessor in interest had or could
-give under the previous paragraph, plus a right to possession of the
-Corresponding Source of the work from the predecessor in interest, if
-the predecessor has it or can get it with reasonable efforts.
-
-  You may not impose any further restrictions on the exercise of the
-rights granted or affirmed under this License.  For example, you may
-not impose a license fee, royalty, or other charge for exercise of
-rights granted under this License, and you may not initiate litigation
-(including a cross-claim or counterclaim in a lawsuit) alleging that
-any patent claim is infringed by making, using, selling, offering for
-sale, or importing the Program or any portion of it.
-
-  11. Patents.
-
-  A "contributor" is a copyright holder who authorizes use under this
-License of the Program or a work on which the Program is based.  The
-work thus licensed is called the contributor's "contributor version".
-
-  A contributor's "essential patent claims" are all patent claims
-owned or controlled by the contributor, whether already acquired or
-hereafter acquired, that would be infringed by some manner, permitted
-by this License, of making, using, or selling its contributor version,
-but do not include claims that would be infringed only as a
-consequence of further modification of the contributor version.  For
-purposes of this definition, "control" includes the right to grant
-patent sublicenses in a manner consistent with the requirements of
-this License.
-
-  Each contributor grants you a non-exclusive, worldwide, royalty-free
-patent license under the contributor's essential patent claims, to
-make, use, sell, offer for sale, import and otherwise run, modify and
-propagate the contents of its contributor version.
-
-  In the following three paragraphs, a "patent license" is any express
-agreement or commitment, however denominated, not to enforce a patent
-(such as an express permission to practice a patent or covenant not to
-sue for patent infringement).  To "grant" such a patent license to a
-party means to make such an agreement or commitment not to enforce a
-patent against the party.
-
-  If you convey a covered work, knowingly relying on a patent license,
-and the Corresponding Source of the work is not available for anyone
-to copy, free of charge and under the terms of this License, through a
-publicly available network server or other readily accessible means,
-then you must either (1) cause the Corresponding Source to be so
-available, or (2) arrange to deprive yourself of the benefit of the
-patent license for this particular work, or (3) arrange, in a manner
-consistent with the requirements of this License, to extend the patent
-license to downstream recipients.  "Knowingly relying" means you have
-actual knowledge that, but for the patent license, your conveying the
-covered work in a country, or your recipient's use of the covered work
-in a country, would infringe one or more identifiable patents in that
-country that you have reason to believe are valid.
-
-  If, pursuant to or in connection with a single transaction or
-arrangement, you convey, or propagate by procuring conveyance of, a
-covered work, and grant a patent license to some of the parties
-receiving the covered work authorizing them to use, propagate, modify
-or convey a specific copy of the covered work, then the patent license
-you grant is automatically extended to all recipients of the covered
-work and works based on it.
-
-  A patent license is "discriminatory" if it does not include within
-the scope of its coverage, prohibits the exercise of, or is
-conditioned on the non-exercise of one or more of the rights that are
-specifically granted under this License.  You may not convey a covered
-work if you are a party to an arrangement with a third party that is
-in the business of distributing software, under which you make payment
-to the third party based on the extent of your activity of conveying
-the work, and under which the third party grants, to any of the
-parties who would receive the covered work from you, a discriminatory
-patent license (a) in connection with copies of the covered work
-conveyed by you (or copies made from those copies), or (b) primarily
-for and in connection with specific products or compilations that
-contain the covered work, unless you entered into that arrangement,
-or that patent license was granted, prior to 28 March 2007.
-
-  Nothing in this License shall be construed as excluding or limiting
-any implied license or other defenses to infringement that may
-otherwise be available to you under applicable patent law.
-
-  12. No Surrender of Others' Freedom.
-
-  If conditions are imposed on you (whether by court order, agreement or
-otherwise) that contradict the conditions of this License, they do not
-excuse you from the conditions of this License.  If you cannot convey a
-covered work so as to satisfy simultaneously your obligations under this
-License and any other pertinent obligations, then as a consequence you may
-not convey it at all.  For example, if you agree to terms that obligate you
-to collect a royalty for further conveying from those to whom you convey
-the Program, the only way you could satisfy both those terms and this
-License would be to refrain entirely from conveying the Program.
-
-  13. Use with the GNU Affero General Public License.
-
-  Notwithstanding any other provision of this License, you have
-permission to link or combine any covered work with a work licensed
-under version 3 of the GNU Affero General Public License into a single
-combined work, and to convey the resulting work.  The terms of this
-License will continue to apply to the part which is the covered work,
-but the special requirements of the GNU Affero General Public License,
-section 13, concerning interaction through a network will apply to the
-combination as such.
-
-  14. Revised Versions of this License.
-
-  The Free Software Foundation may publish revised and/or new versions of
-the GNU General Public License from time to time.  Such new versions will
-be similar in spirit to the present version, but may differ in detail to
-address new problems or concerns.
-
-  Each version is given a distinguishing version number.  If the
-Program specifies that a certain numbered version of the GNU General
-Public License "or any later version" applies to it, you have the
-option of following the terms and conditions either of that numbered
-version or of any later version published by the Free Software
-Foundation.  If the Program does not specify a version number of the
-GNU General Public License, you may choose any version ever published
-by the Free Software Foundation.
-
-  If the Program specifies that a proxy can decide which future
-versions of the GNU General Public License can be used, that proxy's
-public statement of acceptance of a version permanently authorizes you
-to choose that version for the Program.
-
-  Later license versions may give you additional or different
-permissions.  However, no additional obligations are imposed on any
-author or copyright holder as a result of your choosing to follow a
-later version.
-
-  15. Disclaimer of Warranty.
-
-  THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
-APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
-HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
-OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
-THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
-PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
-IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
-ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
-
-  16. Limitation of Liability.
-
-  IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
-WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
-THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
-GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
-USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
-DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
-PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
-EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
-SUCH DAMAGES.
-
-  17. Interpretation of Sections 15 and 16.
-
-  If the disclaimer of warranty and limitation of liability provided
-above cannot be given local legal effect according to their terms,
-reviewing courts shall apply local law that most closely approximates
-an absolute waiver of all civil liability in connection with the
-Program, unless a warranty or assumption of liability accompanies a
-copy of the Program in return for a fee.
-
-                     END OF TERMS AND CONDITIONS
-
-            How to Apply These Terms to Your New Programs
-
-  If you develop a new program, and you want it to be of the greatest
-possible use to the public, the best way to achieve this is to make it
-free software which everyone can redistribute and change under these terms.
-
-  To do so, attach the following notices to the program.  It is safest
-to attach them to the start of each source file to most effectively
-state the exclusion of warranty; and each file should have at least
-the "copyright" line and a pointer to where the full notice is found.

-## About TermSCP 🖥
-
-TermSCP is basically a porting of WinSCP to terminal. So basically is a terminal utility with an TUI to connect to a remote server to retrieve and upload files and to interact with the local file system. It works both on **Linux**, **MacOS**, **BSD** and **Windows** and supports SFTP, SCP, FTP and FTPS.
+Termscp is a feature rich terminal file transfer and explorer, with support for SCP/SFTP/FTP. So basically is a terminal utility with an TUI to connect to a remote server to retrieve and upload files and to interact with the local file system. It is **Linux**, **MacOS**, **BSD** and **Windows** compatible and supports SFTP, SCP, FTP and FTPS.

-### Why TermSCP 🤔
-
-It happens quite often to me, when using SCP at work to forget the path of a file on a remote machine, which forces me then to connect through SSH, gather the file path and finally download it through SCP. I could use WinSCP, but I use Linux and I pratically use the terminal for everything, so I wanted something like WinSCP on my terminal. Yeah, I know there midnight commander too, but actually I don't like it very much tbh (and hasn't a decent support for scp).

-## Usage ❓
+## Buy me a coffee ☕
 
-TermSCP can be started with the following options:
+If you like termscp and you'd love to see the project to grow, please consider a little donation 🥳
 
-- `-P, --password <password>` if address is provided, password will be this argument
-- `-v, --version` Print version info
-- `-h, --help` Print help page
-
-TermSCP can be started in two different mode, if no extra arguments is provided, TermSCP will show the authentication form, where the user will be able to provide the parameters required to connect to the remote peer.
-
-Alternatively, the user can provide an address as argument to skip the authentication form and starting directly the connection to the remote server.
-
-### Address argument
-
-The address argument has the following syntax:
-
-```txt
-[protocol]://[username@]<address>[:port]
-```
-
-Let's see some example of this particular syntax, since it's very comfortable and you'll probably going to use this instead of the other one...
-
-- Connect using default protocol (sftp) to 192.168.1.31, port is default for this protocol (22); username is current user's name
-
-    ```sh
-    termscp 192.168.1.31
-    ```
-
-- Connect using default protocol (sftp) to 192.168.1.31, port is default for this protocol (22); username is `root`
-
-    ```sh
-    termscp root@192.168.1.31
-    ```
-
-- Connect using scp to 192.168.1.31, port is 4022; username is `omar`
-
-    ```sh
-    termscp scp://omar@192.168.1.31:4022
-    ```
-
-#### How Password can be provided
-
-You have probably noticed, that, when providing the address as argument, there's no way to provide the password.
-Password can be basically provided through 3 ways when address argument is provided:
-
-- `-P, --password` option: just use this CLI option providing the password. I strongly unrecommend this method, since it's very unsecure (since you might keep the password in the shell history)
-- Via `sshpass`: you can provide password via `sshpass`, e.g. `sshpass -f ~/.ssh/topsecret.key termscp cvisintin@192.168.1.31`
-- You will be prompted for it: if you don't use any of the previous methods, you will be prompted for the password, as happens with the more classics tools such as `scp`, `ssh`, etc.

 ## Known issues 🧻
 
-- Ftp:
-  - Time in explorer is `1 Jan 1970`, but shouldn't be: that's because chrono can't parse date in a different locale. So if your server has a locale different from the one on your machine, it won't be able to parse the date.
-  - Some servers don't work: yes, some kind of ftp server don't work correctly, sometimes it won't display any files in the directories, some other times uploading files will fail. Up to date, `vsftpd` is the only one server which I saw working correctly with TermSCP. Am I going to solve this? I'd like to, but it's not my fault at all. Unfortunately [rust-ftp](https://github.com/mattnenterprise/rust-ftp) is an abandoned project (up to 2020), indeed I had to patch many stuff by myself. I'll try to solve these issues, but it will take a long time.
-- Sftp:
-  - sftp is much slower than scp: Okay this is an annoying issue, and again: not my fault. It seems there is an issue with [ssh2-rs](https://github.com/alexcrichton/ssh2-rs) library. If you want to stay up to date with the status of this issue, subscribe to [this issue](https://github.com/alexcrichton/ssh2-rs/issues/206)
-- `NoSuchFileOrDirectory` on connect: let me guess, you're running on WSL and you've installed termscp through cargo. I know about this issue and it's a glitch of WSL I guess. Don't worry about it, just move the termscp executable into another PATH location, such as `/usr/bin`.
+- `NoSuchFileOrDirectory` on connect (WSL1): I know about this issue and it's a glitch of WSL I guess. Don't worry about it, just move the termscp executable into another PATH location, such as `/usr/bin`, or install it through the appropriate package format (e.g. deb).

 ## Upcoming Features 🧪
 
-- **Bookmarks and recents**: possibility to save favourites and recent connections to user data, to connect quickly from main menu
-- **Text viewer**: possibility to open and read file both on remote and on local host; this will also support syntax highlighting.
+Major termscp updates will now be seasonal, so expect 4 major updates during the year.
+
+- **Keyring-rs on Linux 🔐**: Planned for the *summer update*, check for updates in [this issue](https://github.com/veeso/termscp/issues/2)
+- **Samba Support 🎉**: This will require a long time to be implemented, since I'm thinking of implementing a Rust native samba library from scratch, since I don't want to add new C-bindings. It'll maybe included in the *summer update*.
+- **Themes provider 🎨**: I'm still thinking about how I will implement this, but basically the idea is to have a configuration file where it will be possible to define the color schema for the entire application. I haven't planned this release yet
+- **Configuration profile for bookmarks 📚**: I would like to, but I still have to analyze it.
+- **AWS S3 support 🪣**: There is already a library for AWS S3, but this is really on bottom of my implementation list at the moment, due to interest and I don't really have a system where to test it.
+
+Along to new features, termscp developments is now focused on UI and performance improvements, so if you have any suggestion, feel free to open an issue.

+
+Welcome to the developer manual for termscp. This chapter DOESN'T contain the documentation for termscp modules, which can instead be found on Rust Docs at <https://docs.rs/termscp>
+This chapter describes how termscp works and the guide lines to implement stuff such as file transfers and add features to the user interface.
+
+## How termscp works
+
+termscp is basically made up of 4 components:
+
+- the **filetransfer**: the filetransfer takes care of managing the remote file system; it provides function to establish a connection with the remote, operating on the remote server file system (e.g. remove files, make directories, rename files, ...), read files and write files. The FileTransfer, as we'll see later, is actually a trait, and for each protocol a FileTransfer must be implement the trait.
+- the **host**: the host module provides functions to interact with the local host file system.
+- the **ui**: this module contains the implementation of the user interface, as we'll see in the next chapter, this is achieved through **activities**.
+- the **activity_manager**: the activity manager takes care of managing activities, basically it runs the activities of the user interface, and chooses, based on their state, when is the moment to terminate the current activity and which activity to run after the current one.
+
+In addition to the 4 main components, other have been added through the time:
+
+- **config**: this module provides the configuration schema and serialization methods for it.
+- **fs**: this modules exposes the FsEntry entity and the explorers. The explorers are structs which hold the content of the current directory; they also they take of filtering files up to your preferences and format file entries based on your configuration.
+- **system**: the system module provides a way to actually interact with the configuration, the ssh key storage and with the bookmarks.
+- **utils**: contains the utilities used by pretty much all the project.
+
+## Activities
+
+Just a little paragraph about activities. Really, read the code and the documentation to have a clear idea of how the ui works.
+I think there are many ways to implement a user interface and I've worked with different languages and frameworks in my career, so for this project I've decided to get what I like the most from different frameworks to implement it.
+
+My approach was this:
+
+- **Activities on top**: each "page" is an Activity and an `Activity Manager` handles them. I got inspired by Android for this case. I think that's a good way to implement the ui in case like this, where you have different pages, each one with their view, their components and their logics. Activities work with the `Context`, which is a data holder for different data, which are shared and common between the activities.
+- **Activities display Views**: Each activity can show different views. A view is basically a list of **components**, each one with its properties. The view is a facade to the components and also handles the focus, which is the current active component. You cannot have more than one component active, so you need to handle this; but at the same time you also have to give focus to the previously active component if the current one is destroyed. So basically view takes care of all this stuff.
+- **Components**: I've decided to write around `tui` in order to re-use widgets. To do so I've implemented the `Component` trait. To implement traits I got inspired by [React](https://reactjs.org/). Each component has its *Properties* and can have its *States*. Then each component must be able to handle input events and to be updated with new properties. Last but not least, each component must provide a method to **render** itself.
+- **Messages: an Elm based approach**: I was really satisfied with my implementation choices; the problem at this point was solving one of the biggest teardrops I've ever had with this project: **events**. Input events were really a pain to handle, since I had to handle states in the activity to handle which component was enabled etc. To solve this I got inspired by a wonderful language I had recently studied, which is [Elm](https://elm-lang.org/). Basically in Elm you implement your ui using three basic functions: **update**, **view** and **init**. View and init were pretty much already implemented here, but at this point I decided to implement also something like the **elm update function**. I came out with a huge match case to handle events inside a recursive function, which you can basically find in the `update.rs` file inside each activity. This match case handles a tuple, made out of the **component id** and the **input event** received from the view. It matches the two propeties against the input event we want to handle for each component *et voilà*.
+
+I've implemented a Trait called `Activity`, which, is a very very reduced version of the Android activity of course.
+This trait provides only 3 methods:
+
+- `on_create`: this method must initialize the activity; the context is passed to the activity, which will be the only owner of the Context, until the activity terminates.
+- `on_draw`: this method must be called each time you want to perform an update of the user interface. This is basically the run method of the activity. This method also cares about handling input events. The developer shouldn't draw the interface on each call of this method (consider that this method might be called hundreds of times per second), but only when actually something has changed (for example after an input event has been raised).
+- `will_umount`: this method was added in 0.4.0 and returns whethere the activity should be destroyed. If so returns an ExitReason, which indicates why the activity should be terminated. Based on the reason, the activity manager chooses whether to stop the execution of termscp or to start a new activity and which one.
+- `on_destroy`: this method finalizes the activity and drops it; this method returns the Context to the caller (the activity manager).
+
+### The Context
+
+The context is a structure which holds data which must be shared between activities. Everytime an Activity starts, the Context is taken by the activity, until it is destroyed, where finally the context is returned to the activity manager.
+The context basically holds the following data:
+
+- The **Localhost**: the local host structure
+- The **File Transfer Params**: the current parameters set to connect to the remote
+- The **Config Client**: the configuration client is a structure which provides functions to access the user configuration
+- The **Store**: the store is a key-value storage which can hold any kind of data. This can be used to store states to share between activities or to keep persistence for heavy/slow tasks (such as checking for updates).
+- The **Input handler**: the input handler is used to read input events from the keyboard
+- The **Terminal**: the terminal is used to view the tui on the terminal

+
+## Tests fails due to receivers
+
+Yes. This happens quite often and is related to the fact that I'm using public SSH/SFTP/FTP server to test file receivers and sometimes this server go down for even a day or more. If your tests don't pass due to this, don't worry, submit the pull request and I'll take care of testing them by myself.
+
+---
+
+## Implementing File Transfers
+
+This chapter describes how to implement a file transfer in termscp. A file transfer is a module which implements the `FileTransfer` trait. The file transfer provides different modules to interact with a remote server, which in addition to the most obvious methods, used to download and upload files, provides also methods to list files, delete files, create directories etc.
+
+In the following steps I will describe how to implement a new file transfer, in this case I will be implementing the SCP file transfer (which I'm actually implementing the moment I'm writing this lines).
+
+1. Add the Scp protocol to the `FileTransferProtocol` enum.
+
+    Move to `src/filetransfer/mod.rs` and add `Scp` to the `FileTransferProtocol` enum
+
+    ```rs
+    /// ## FileTransferProtocol
+    ///
+    /// This enum defines the different transfer protocol available in termscp
+    #[derive(std::cmp::PartialEq, std::fmt::Debug, std::clone::Clone)]
+    pub enum FileTransferProtocol {
+        Sftp,
+        Ftp(bool), // Bool is for secure (true => ftps)
+        Scp, // <-- here
+    }
+    ```
+
+    In this case Scp is a "plain" enum type. If you need particular options, follow the implementation of `Ftp` which uses a boolean flag for indicating if using FTPS or FTP.
+
+2. Implement the FileTransfer struct
+
+    Create a file at `src/filetransfer/mytransfer.rs`
+
+    Declare your file transfer struct
+
+    ```rs
+    /// ## ScpFileTransfer
+    ///
+    /// SFTP file transfer structure
+    pub struct ScpFileTransfer {
+        session: Option<Session>,
+        sftp: Option<Sftp>,
+        wrkdir: PathBuf,
+    }
+    ```
+
+3. Implement the `FileTransfer` trait for it
+
+    You'll have to implement the following methods for your file transfer:
+
+    - connect: connect to remote server
+    - disconnect: disconnect from remote server
+    - is_connected: returns whether the file transfer is connected to remote
+    - pwd: get working directory
+    - change_dir: change working directory.
+    - list_dir: get files and directories at a certain path
+    - mkdir: make a new directory. Return an error in case the directory already exists
+    - remove: remove a file or a directory. In case the protocol doesn't support recursive removing of directories you MUST implement this through a recursive algorithm
+    - rename: rename a file or a directory
+    - stat: returns detail for a certain path
+    - send_file: opens a stream to a remote path for write purposes (write a remote file)
+    - recv_file: opens a stream to a remote path for read purposes (write a local file)
+    - on_sent: finalize a stream when writing a remote file. In case it's not necessary just return `Ok(())`
+    - on_recv: fianlize a stream when reading a remote file. In case it's not necessary just return `Ok(())`
+
+    In case the protocol you're working on doesn't support any of this features, just return `Err(FileTransferError::new(FileTransferErrorType::UnsupportedFeature))`
+
+4. Add your transfer to filetransfers:
+
+    Move to `src/filetransfer/mod.rs` and declare your file transfer:
+
+    ```rs
+    // Transfers
+    pub mod ftp_transfer;
+    pub mod scp_transfer; // <-- here
+    pub mod sftp_transfer;
+    ```
+
+5. Handle FileTransfer in `FileTransferActivity::new`
+
+    Move to `src/ui/activities/filetransfer_activity/mod.rs` and add the new protocol to the client match
+
+    ```rs
+    client: match protocol {
+        FileTransferProtocol::Sftp => Box::new(SftpFileTransfer::new()),
+        FileTransferProtocol::Ftp(ftps) => Box::new(FtpFileTransfer::new(ftps)),
+        FileTransferProtocol::Scp => Box::new(ScpFileTransfer::new()), // <--- here
+    },
+    ```
+
+6. Handle right/left input events in `AuthActivity`:
+
+    Move to `src/ui/activities/auth_activity.rs` and handle the new protocol in `handle_input_event_mode_text` for `KeyCode::Left` and `KeyCode::Right`.
+    Consider that the order they "rotate" must match the way they will be drawned in the interface.
+    For newer protocols, please put them always at the end of the list. In this list I won't, because Scp is more important than Ftp imo.
+
+    ```rs
+    KeyCode::Left => {
+        // If current field is Protocol handle event... (move element left)
+        if self.selected_field == InputField::Protocol {
+            self.protocol = match self.protocol {
+                FileTransferProtocol::Sftp => FileTransferProtocol::Ftp(true), // End of list (wrap)
+                FileTransferProtocol::Scp => FileTransferProtocol::Sftp,
+                FileTransferProtocol::Ftp(ftps) => match ftps {
+                    false => FileTransferProtocol::Scp,
+                    true => FileTransferProtocol::Ftp(false),
+                }
+            };
+        }
+    }
+    KeyCode::Right => {
+        // If current field is Protocol handle event... ( move element right )
+        if self.selected_field == InputField::Protocol {
+            self.protocol = match self.protocol {
+                FileTransferProtocol::Sftp => FileTransferProtocol::Scp,
+                FileTransferProtocol::Scp => FileTransferProtocol::Ftp(false),
+                FileTransferProtocol::Ftp(ftps) => match ftps {
+                    false => FileTransferProtocol::Ftp(true),
+                    true => FileTransferProtocol::Sftp, // End of list (wrap)
+                }
+            };
+        }
+    }
+    ```
+
+7. Add your new file transfer to the protocol input field
+
+    Move to `AuthActivity::draw_protocol_select` method.
+    Here add your new protocol to the `Spans` vector and to the match case, which chooses which element to highlight.
+
+    ```rs
+    let protocols: Vec<Spans> = vec![Spans::from("SFTP"), Spans::from("SCP"), Spans::from("FTP"), Spans::from("FTPS")];
+    let index: usize = match self.protocol {
+        FileTransferProtocol::Sftp => 0,
+        FileTransferProtocol::Scp => 1,
+        FileTransferProtocol::Ftp(ftps) => match ftps {
+            false => 2,
+            true => 3,
+        }
+    };
+    ```

+# User manual 🎓
+
+## Usage ❓
+
+termscp can be started with the following options:
+
+`termscp [options]... [protocol://user@address:port:wrkdir] [local-wrkdir]`
+
+- `-P, --password <password>` if address is provided, password will be this argument
+- `-q, --quiet` Disable logging
+- `-v, --version` Print version info
+- `-h, --help` Print help page
+
+termscp can be started in two different mode, if no extra arguments is provided, termscp will show the authentication form, where the user will be able to provide the parameters required to connect to the remote peer.
+
+Alternatively, the user can provide an address as argument to skip the authentication form and starting directly the connection to the remote server.
+
+If address argument is provided you can also provide the start working directory for local host
+
+### Address argument 🌎
+
+The address argument has the following syntax:
+
+```txt
+[protocol://][username@]<address>[:port][:wrkdir]
+```
+
+Let's see some example of this particular syntax, since it's very comfortable and you'll probably going to use this instead of the other one...
+
+- Connect using default protocol (*defined in configuration*) to 192.168.1.31, port if not provided is default for the selected protocol (in this case depends on your configuration); username is current user's name
+
+    ```sh
+    termscp 192.168.1.31
+    ```
+
+- Connect using default protocol (*defined in configuration*) to 192.168.1.31; username is `root`
+
+    ```sh
+    termscp root@192.168.1.31
+    ```
+
+- Connect using scp to 192.168.1.31, port is 4022; username is `omar`
+
+    ```sh
+    termscp scp://omar@192.168.1.31:4022
+    ```
+
+- Connect using scp to 192.168.1.31, port is 4022; username is `omar`. You will start in directory `/tmp`
+
+    ```sh
+    termscp scp://omar@192.168.1.31:4022:/tmp
+    ```
+
+#### How Password can be provided 🔐
+
+You have probably noticed, that, when providing the address as argument, there's no way to provide the password.
+Password can be basically provided through 3 ways when address argument is provided:
+
+- `-P, --password` option: just use this CLI option providing the password. I strongly unrecommend this method, since it's very unsecure (since you might keep the password in the shell history)
+- Via `sshpass`: you can provide password via `sshpass`, e.g. `sshpass -f ~/.ssh/topsecret.key termscp cvisintin@192.168.1.31`
+- You will be prompted for it: if you don't use any of the previous methods, you will be prompted for the password, as happens with the more classics tools such as `scp`, `ssh`, etc.
+
+---
+
+## File explorer 📂
+
+When we refer to file explorers in termscp, we refer to the panels you can see after establishing a connection with the remote.
+These panels are basically 3 (yes, three actually):
+
+- Local explorer panel: it is displayed on the left of your screen and shows the current directory entries for localhost
+- Remote explorer panel: it is displayed on the right of your screen and shows the current directory entries for the remote host.
+- Find results panel: depending on where you're searching for files (local/remote) it will replace the local or the explorer panel. This panel shows the entries matching the search query you performed.
+
+In order to change panel you need to type `<LEFT>` to move the remote explorer panel and `<RIGHT>` to move back to the local explorer panel. Whenever you are in the find results panel, you need to press `<ESC>` to exit panel and go back to the previous panel.
+

+
+### Work on multiple files 🥷
+
+You can opt to work on multiple files, selecting them pressing `<M>`, in order to select the current file, or pressing `<CTRL+A>`, which will select all the files in the working directory.
+Once a file is marked for selection, it will be displayed with a `*` on the left.
+When working on selection, only selected file will be processed for actions, while the current highlighted item will be ignored.
+It is possible to work on multiple files also when in the find result panel.
+All the actions are available when working with multiple files, but be aware that some actions work in a slightly different way. Let's dive in:
+
+- *Copy*: whenever you copy a file, you'll be prompted to insert the destination name. When working with multiple file, this name refers to the destination directory where all these files will be copied.
+- *Rename*: same as copy, but will move files there.
+- *Save as*: same as copy, but will write them there.
+
+### Synchronized browsing ⏲️
+
+When enabled, synchronized browsing, will allow you to synchronize the navigation between the two panels.
+This means that whenever you'll change the working directory on one panel, the same action will be reproduced on the other panel. If you want to enable synchronized browsing just press `<Y>`; press twice to disable. While enabled, the synchronized browising state will be reported on the status bar on `ON`.
+
+*Warning*: at the moment, whenever you try to access an unexisting directory, you won't be prompted to create it. This might change in a future update.
+

+
+## Bookmarks ⭐
+
+In termscp it is possible to save favourites hosts, which can be then loaded quickly from the main layout of termscp.
+termscp will also save the last 16 hosts you connected to.
+This feature allows you to load all the parameters required to connect to a certain remote, simply selecting the bookmark in the tab under the authentication form.
+
+Bookmarks will be saved, if possible at:
+
+- `$HOME/.config/termscp/` on Linux/BSD
+- `$HOME/Library/Application Support/termscp` on MacOs
+- `FOLDERID_RoamingAppData\termscp\` on Windows
+
+For bookmarks only (this won't apply to recent hosts) it is also possible to save the password used to authenticate. The password is not saved by default and must be specified through the prompt when saving a new Bookmark.
+
+> I was very undecided about storing passwords in termscp. The reason? Saving a password on your computer might give access to a hacker to any server you've registered. But I must admit by myself that for many machines typing the password everytime is really boring, also many times I have to work with machines in LAN, which wouldn't provide any advantage to an attacker, So I came out with a good compromise for passwords.
+
+I warmly suggest you to follow these guidelines in order to decide whether you should or you shouldn't save passwords:
+
+- **DON'T** save passwords for machines which are exposed on the internet, save passwords only for machines in LAN
+- Make sure your machine is protected by attackers. If possible encrypt your disk and don't leave your PC unlocked while you're away.
+- Preferably, save passwords only when a compromising of the target machine wouldn't be a problem.
+
+In order to create a new bookmark, just follow these steps:
+
+1. Type in the authentication form the parameters to connect to your remote server
+2. Press `<CTRL+S>`
+3. Type in the name you want to give to the bookmark
+4. Choose whether to remind the password or not
+5. Press `<ENTER>` to submit
+
+whenever you want to use the previously saved connection, just press `<TAB>` to navigate to the bookmarks list and load the bookmark parameters into the form pressing `<ENTER>`.
+
+![Bookmarks](https://github.com/veeso/termscp/blob/main/assets/images/bookmarks.gif?raw=true)
+
+### Are my passwords Safe 😈
+
+Well, kinda.
+As said before, bookmarks are saved in your configuration directory along with passwords. Passwords are obviously not plain text, they are encrypted with **AES-128**. Does this make them safe? Well, depends on your operating system:
+
+On Windows and MacOS the passwords are stored, if possible (but should be), in respectively the Windows Vault and the Keychain. This is actually super-safe and is directly managed by your operating system.
+
+On Linux and BSD, on the other hand, the key used to encrypt your passwords is stored on your drive (at $HOME/.config/termscp). It is then, still possible to retrieve the key to decrypt passwords. Luckily, the location of the key guarantees your key can't be read by users different from yours, but yeah, I still wouldn't save the password for a server exposed on the internet 😉.
+Actually [keyring-rs](https://github.com/hwchen/keyring-rs), supports Linux, but for different reasons I preferred not to make it available for this configuration. If you want to read more about my decision read [this issue](https://github.com/veeso/termscp/issues/2), while if you think this might have been implemented differently feel free to open an issue with your proposal.
+
+---
+
+## Configuration ⚙️
+
+termscp supports some user defined parameters, which can be defined in the configuration.
+Underhood termscp has a TOML file and some other directories where all the parameters will be saved, but don't worry, you won't touch any of these files manually, since I made possible to configure termscp from its user interface entirely.
+
+termscp, like for bookmarks, just requires to have these paths accessible:
+
+- `$HOME/.config/termscp/` on Linux/BSD
+- `$HOME/Library/Application Support/termscp` on MacOs
+- `FOLDERID_RoamingAppData\termscp\` on Windows
+
+To access configuration, you just have to press `<CTRL+C>` from the home of termscp.
+
+These parameters can be changed:
+
+- **Text Editor**: the text editor to use. By default termscp will find the default editor for you; with this option you can force an editor to be used (e.g. `vim`). **Also GUI editors are supported**, unless they `nohup` from the parent process so if you ask: yes, you can use `notepad.exe`, and no: **Visual Studio Code doesn't work**.
+- **Default Protocol**: the default protocol is the default value for the file transfer protocol to be used in termscp. This applies for the login page and for the address CLI argument.
+- **Show Hidden Files**: select whether hidden files shall be displayed by default. You will be able to decide whether to show or not hidden files at runtime pressing `A` anyway.
+- **Check for updates**: if set to `yes`, termscp will fetch the Github API to check if there is a new version of termscp available.
+- **Group Dirs**: select whether directories should be groupped or not in file explorers. If `Display first` is selected, directories will be sorted using the configured method but displayed before files, viceversa if `Display last` is selected.
+- **File formatter syntax**: syntax to display file info for each file in the explorer. See [File explorer format](#file-explorer-format)
+
+### SSH Key Storage 🔐
+
+Along with configuration, termscp provides also an **essential** feature for **SFTP/SCP clients**: the SSH key storage.
+
+You can access the SSH key storage, from configuration moving to the `SSH Keys` tab, once there you can:
+
+- **Add a new key**: just press `<CTRL+N>` and you will be prompted to create a new key. Provide the hostname/ip address and the username associated to the key and finally a text editor will open up: paste the **PRIVATE** ssh key into the text editor, save and quit.
+- **Remove an existing key**: just press `<DEL>` or `<CTRL+E>` on the key you want to remove, to delete persistently the key from termscp.
+- **Edit an existing key**: just press `<ENTER>` on the key you want to edit, to change the private key.
+
+> Q: Wait, my private key is protected with password, can I use it?  
+> A: Of course you can. The password provided for authentication in termscp, is valid both for username/password authentication and for RSA key authentication.
+
+### File Explorer Format
+
+It is possible through configuration to define a custom format for the file explorer. This is possible both for local and remote host, so you can have two different syntax in use. These fields, with name `File formatter syntax (local)` and `File formatter syntax (remote)` will define how the file entries will be displayed in the file explorer.
+The syntax for the formatter is the following `{KEY1}... {KEY2:LENGTH}... {KEY3:LENGTH:EXTRA} {KEYn}...`.
+Each key in bracket will be replaced with the related attribute, while everything outside brackets will be left unchanged.
+
+- The key name is mandatory and must be one of the keys below
+- The length describes the length reserved to display the field. Static attributes doesn't support this (GROUP, PEX, SIZE, USER)
+- Extra is supported only by some parameters and is an additional options. See keys to check if extra is supported.
+
+These are the keys supported by the formatter:
+
+- `ATIME`: Last access time (with default syntax `%b %d %Y %H:%M`); Extra might be provided as the time syntax (e.g. `{ATIME:8:%H:%M}`)
+- `CTIME`: Creation time (with syntax `%b %d %Y %H:%M`); Extra might be provided as the time syntax (e.g. `{CTIME:8:%H:%M}`)
+- `GROUP`: Owner group
+- `MTIME`: Last change time (with syntax `%b %d %Y %H:%M`); Extra might be provided as the time syntax (e.g. `{MTIME:8:%H:%M}`)
+- `NAME`: File name (Elided if longer than 24)
+- `PEX`: File permissions (UNIX format)
+- `SIZE`: File size (omitted for directories)
+- `SYMLINK`: Symlink (if any `-> {FILE_PATH}`)
+- `USER`: Owner user
+
+If left empty, the default formatter syntax will be used: `{NAME:24} {PEX} {USER} {SIZE} {MTIME:17:%b %d %Y %H:%M}`
+
+---
+
+## Text Editor ✏
+
+termscp has, as you might have noticed, many features, one of these is the possibility to view and edit text file. It doesn't matter if the file is located on the local host or on the remote host, termscp provides the possibility to open a file in your favourite text editor.
+In case the file is located on remote host, the file will be first downloaded into your temporary file directory and then, **only** if changes were made to the file, re-uploaded to the remote host. termscp checks if you made changes to the file verifying the last modification time of the file.
+
+Just a reminder: **you can edit only textual file**; binary files are not supported.
+
+### How do I configure the text editor 🦥
+
+Text editor is automatically found using this [awesome crate](https://github.com/milkey-mouse/edit), if you want to change the text editor to use, change it in termscp configuration. [Read more](#configuration-️)
+
+---
+
+## Logging 🩺
+
+termscp writes a log file for each session, which is written at
+
+- `$HOME/.config/termscp/termscp.log` on Linux/BSD
+- `$HOME/Library/Application Support/termscp/termscp.log` on MacOs
+- `FOLDERID_RoamingAppData\termscp\termscp.log` on Windows
+
+the log won't be rotated, but will just be truncated after each launch of termscp, so if you want to report an issue and you want to attach your log file, keep in mind to save the log file in a safe place before using termscp again.
+The log file always reports in *trace* level, so it is kinda verbose.
+I know you might have some questions regarding log files, so I made a kind of a Q/A:
+
+> Is it possible to reduce verbosity?
+
+No. The reason is quite simple: when an issue happens, you must be able to know what's causing it and the only way to do that, is to have the log file with the maximum verbosity level set.
+
+> If trace level is set for logging, is the file going to reach a huge size?
+
+Probably not, unless you never quit termscp, but I think that's likely to happne. A long session may produce up to 10MB of log files (I said a long session), but I think a normal session won't exceed 2MB.
+
+> I don't want logging, can I turn it off?
+
+Yes, you can. Just start termscp with `-q or --quiet` option. You can alias termscp to make it persistent. Remember that logging is used to diagnose issues, so since behind every open source project, there should always be this kind of mutual help, keeping log files might be your way to support the project 😉. I don't want you to feel guilty, but just to say.
+
+> Is logging safe?
+
+If you're concerned about security, the log file doesn't contain any plain password, so don't worry and exposes the same information the sibling file `bookmarks` reports.
