kdocker is a utility that allows you to dock almost any application into the system tray (also known as the notification area). This is particularly useful for applications that don't natively support system tray integration. By launching an application via kdocker, its window will be hidden from the taskbar, and instead, an icon representing the application will appear in the system tray.

This can help reduce clutter on your taskbar and provide a more discreet way to manage running applications. kdocker essentially 'reparents' the application window to the system tray. When the user clicks on the system tray icon, the original application window is restored (or a menu of options is provided, depending on the application and kdocker's configuration). kdocker is mostly used for legacy applications that doesn't support system tray docking.

kdocker may not work perfectly with all applications. Some applications may have unexpected behavior when docked, or may not be dockable at all. Compatibility depends on the application and the window manager used.

It depends on X11 and therefore won't function properly on Wayland without XWayland.

Docking the application 'firefox':
kdocker firefox

Docking with a specified icon and title:
kdocker -i /path/to/icon.png -t "My Application" myapp

kdocker emerged as a solution to provide system tray functionality for applications predating widespread system tray integration. It gained popularity among users of older or less feature-rich window managers or desktop environments. Its usage has decreased with more modern applications and desktop environments natively supporting system tray functionality.
