approx. 90% are already translated. At the moment 2 languages are included. English and German. If you are interested, feel free to add more translations. See the maintenance.php for more information. The Frontend is almost done. Some translations in the notification system are still pending.
I am aware that the language files still have some optimization potential, but after 3 days of localization, I don't feel like doing that right now.
Because of my own network structure an automatic nmap scan is not useful. However, to be able to perform such a scan if necessary, I have added a tab with a manual nmap scan in the DeviceDetails.
