matchbox-applet-startup-monitor 0.1: Try to support management using matchbox-panel-manager.
* It seems this thing is standalone misfit which is supposed to be simply run
during session startup ;-\. Try to add at least bit of user configurability. With
this desktop file, it is at least possible to add it via context menu on
matchbox-panel. But it doesn't seem to get recorded in panel settings, so
cannot be removed via menu and its unclear if it will be restarted after
reboot ;-(.
