- applets/systemtray: Should background apps as reported by org.freedesktop.BackgroundMonitor
Some apps rely on the shell showing this info - they just vanish when clicking the window but keep on running and continue for example to play music. Without us displaying the app somewhere this is very confusing to the user and there exist no other way to bring them back short of "launching" the app gain which is not very intuitive either. Note that only flatpaks are currently reported through this mechanism. A proxy model also makes sure that we do not display a duplicate entry for an app if it itself registers a SNI.
