This is a feature request. I would like to be able to show selected applications in the system tray, instead than as a task manager button, when minimized.

This behavior is very handy for daemon-like applications, where you use the GUI only upon notifications, such as Thunderbird, a running music player etc.

Currently this behavior can be achieved through third-party programs such as KDocker. However:

- KDocker and similar programs do not work on Wayland, and AFAIK cannot, due to protocol restrictions
- Plasmashell would be much easier and more flexible than KDocker for the user. User shall be able to:
  - right-click on the taskbar button, and "send application to System Tray"
  - define a rule for the application, so that it is automatically started in the system tray, etc.
