+- **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)

 > 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.

-## 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.

-### 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 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 is 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 🥳
 
-`termscp [options]... [protocol://user@address:port:wrkdir] [local-wrkdir]`
-
-- `-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.
-
-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.
-

-
-## 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.
-
-To create a bookmark, just fulfill the authentication form and then input `<CTRL+S>`; you'll then be asked to give a name to your bookmark, and tadah, the bookmark has been created.
-If you go to [gallery](#gallery-), there is a GIF showing how bookmarks work 💪.
-
-### 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.

-
-## 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. [View more](#configuration-️)
-
----
-
-## 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, 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:
-
-- **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.
-- **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**.
-- **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.
-
-### 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 field, with name `File formatter syntax` 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}`

 ## Known issues 🧻
 
-- `NoSuchFileOrDirectory` on connect (WSL): 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 🧪
 
-- **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
-- **Local and remote file explorer format 🃏**: From 0.5.0 you will be able to customize the file format for both local and remote hosts.
-- **Synchronized browsing of local and remote directories ⌚**: See [Issue 8](https://github.com/veeso/termscp/issues/8)
-- **Group file select 🤩**: Possibility to select a group of files in explorers to operate on
+Major termscp releases will now be seasonal, so expect 4 major updates during the year.
 
-No other new feature is planned at the moment. I actually think that termscp is getting mature and now I should focus upcoming updates more on bug fixing and
-code/performance improvements than on new features.
-Anyway there are some ideas which I'd like to implement. If you want to start working on them, feel free to open a PR:
+Planned for *🍁 Autumn update 🍇*:
 
-- Amazon S3 support
-- Samba support
-- Themes provider
+- **Self-update ⬇️**: In order to increase users updating termscp, I want to provide the possibility to  update termscp directly from application, when a new update is available.
+- **AWS S3 support 🪣**: I'll use `rust-s3` library to implement this. This is really big **Maybe** for the autumn update and might be moved to the Winter update.
+- **Prompt before replacing files ☢️**: Possibility to configure whether a prompt should be displayed before replacing files.
+
+Planned for *❄️ Winter update ⛄*:
+
+- **SMB Support 🎉**: This will require a long time to be implemented, since I'm currently working on a Rust native SMB library, since I don't want to add new C-bindings. ~~Fear the 🦚~~
+- **Configuration profile for bookmarks 📚**: Basically this feature adds the possibility to have a specific setup for a certain host, instead of having only one global configuration.
+
+Along to new features, termscp developments is now focused on UX and performance improvements, so if you have any suggestion, feel free to open an issue.

+
+Usually it's enough to run `cargo test`, but please note that whenever you're working on file transfer you'll need one more step.
+In order to run tests with file transfers, you need to start the file transfer server containers, which can be started via `docker`.
+
+To run all tests with file transfers just run: `./tests/test.sh`

+## 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.

-## 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,
-        }
-    };
-    ```

+
+## 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
+- `-c, --config` Open termscp starting from the configuration page
+- `-q, --quiet` Disable logging
+- `-t, --theme <path>` Import specified theme
+- `-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.
+
+### Open and Open With 🚪
+
+Open and open with commands are powered by [open-rs](https://docs.rs/crate/open/1.7.0).
+When opening files with View command (`<V>`), the system default application for the file type will be used. To do so, the default operting system service will be used, so be sure to have at least one of these installed on your system:
+
+- **Windows** users: you don't have to worry about it, since the crate will use the `start` command.
+- **MacOS** users: you don't have to worry either, since the crate will use `open`, which is already installed on your system.
+- **Linux** users: one of these should be installed
+  - *xdg-open*
+  - *gio*
+  - *gnome-open*
+  - *kde-open*
+- **WSL** users: *wslview* is required, you must install [wslu](https://github.com/wslutilities/wslu).
+
+> Q: Can I edit remote files using the view command?  
+> A: No, at least not directly from the "remote panel". You have to download it to a local directory first, that's due to the fact that when you open a remote file, the file is downloaded into a temporary directory, but there's no way to create a watcher for the file to check when the program you used to open it was closed, so termscp is not able to know when you're done editing the file.
+
+---
+
+## 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, Yep 😉.
+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? Absolutely! (except for BSD and WSL users 😢)
+
+On **Windows**, **Linux** and **MacOS** the passwords are stored, if possible (but should be), respectively in the *Windows Vault*, in the *system keyring* and into the *Keychain*. This is actually super-safe and is directly managed by your operating system.
+
+❗ Please, notice that if you're a Linux user, you should really read the [chapter below 👀](#linux-keyring), because the keyring might not be enabled or supported on your system!
+
+On *BSD* and *WSL*, 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 😉.
+
+#### Linux Keyring
+
+We all love Linux thanks to the freedom it gives to the users. You can basically do anything you want as a Linux user, but this has also some cons, such as the fact that often there is no standard applications across different distributions. And this involves keyring too.
+This means that on Linux there might be no keyring installed on your system. Unfortunately the library we use to work with the key storage requires a service which exposes `org.freedesktop.secrets` on D-BUS and the worst fact is that there only two services exposing it.
+
+- ❗ If you use GNOME as desktop environment (e.g. ubuntu users), you should already be fine, since keyring is already provided by `gnome-keyring` and everything should already be working.
+- ❗ For other desktop environment users there is a nice program you can use to get a keyring which is [KeepassXC](https://keepassxc.org/), which I use on my Manjaro installation (with KDE) and works fine. The only problem is that you have to setup it to be used along with termscp (but it's quite simple). To get started with KeepassXC read more [here](#keepassxc-setup-for-termscp).
+- ❗ What about you don't want to install any of these services? Well, there's no problem! **termscp will keep working as usual**, but it will save the key in a file, as it usually does for BSD and WSL.
+
+##### KeepassXC setup for termscp
+
+Follow these steps in order to setup keepassXC for termscp:
+
+1. Install KeepassXC
+2. Go to "tools" > "settings" in toolbar
+3. Select "Secret service integration" and toggle "Enable KeepassXC freedesktop.org secret service integration"
+4. Create a database, if you don't have one yet: from toolbar "Database" > "New database"
+5. From toolbar: "Database" > "Database settings"
+6. Select "Secret service integration" and toggle "Expose entries under this group"
+7. Select the group in the list where you want the termscp secret to be kept. Remember that this group might be used by any other application to store secrets via DBUS.
+
+---
+
+## 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.
+- **Remote File formatter syntax**: syntax to display file info for each file in the remote explorer. See [File explorer format](#file-explorer-format)
+- **Local File formatter syntax**: syntax to display file info for each file in the local 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}`
+
+---
+
+## Themes 🎨
+
+Termscp provides you with an awesome feature: the possibility to set the colors for several components in the application.
+If you want to customize termscp there are two available ways to do so:
+
+- From the **configuration menu**
+- Importing a **theme file**
+
+In order to create your own customization from termscp, all you have to do so is to enter the configuration from the auth activity, pressing `<CTRL+C>` and then `<TAB>` twice. You should have now moved to the `themes` panel.
+
+Here you can move with `<UP>` and `<DOWN>` to change the style you want to change, as shown in the gif below:
+
+![Themes](../assets/images/themes.gif)
+
+termscp supports both the traditional explicit hex (`#rrggbb`) and rgb `rgb(r, g, b)` syntax to provide colors, but also **[css colors](https://www.w3schools.com/cssref/css_colors.asp)** (such as `crimson`) are accepted 😉. There is also a special keywork which is `Default`. Default means that the color used will be the default foreground or background color based on the situation (foreground for texts and lines, background for well, guess what).
+
+As said before, you can also import theme files. You can take inspiration from or directly use one of the themes provided along with termscp, located in the `themes/` directory of this repository and import them running termscp as `termscp -t <theme_file>`. If everything was fine, it should tell you the theme has successfully been imported.
+
+### Styles 💈

+## 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.
