Add:
Message history support and saving of history to file (also: loading history
        at startup).
TCP support
gnome panel support
	(Similar to GTKICQ, but configurable so that a double-click means
	 either "open full window" or "read waiting message")
gnome_appbar support
	http://www.gnome.org/devel/gnome-dev-info/gnomeappbar.html
	(for "please wait, working" or "searching"; tell the user what's
	 going on here, instead of (or on top of) debugging to the console)
gnome_appbar support
	(for progress meter too) :)
