With version 1.4.4 trayicon has been re-introduced. However it's only possible to either en- or disable it. I like to suggestion an option to only show the trayicon if on battery. I also think this should be the default setting. Suggestions aroused from https://bugzilla.redhat.com/show_bug.cgi?id=1211041 Kind Regards Woi
Sorry, I consider the trayicon legacy and won't add any new features to it.
