show (not) supported features in one place
when you run gajim from a terminal, you get messages like
gpg: not found
Session Management support not available (missing gnome.ui module)
Network Manager support not available
but what about when you don't run gajim from a terminal? you won't know that network manager support or such does not work.
it would be nice to have a dialog somewhere, where you have a list of supported features like gpg, session management, zeroconf, dbus, network manager and so on with an icon next to it so you can see if the feature works or if it does not.
