Key Features:

Moreover...

Tested on Ubuntu 25.04, built on Debian 10 (.deb package). Because this project was conceived for Ubuntu, so for GNOME desktop environment, the application is fully compatible with Ubuntu. In particular the enable/disable "Do Not Disturb" feature is available only on Ubuntu. The same feature is not available on Windows because there are important changes between Windows 10 and Windows 11 and frankly, I need more time in order to learn Windows API.
