Comment 9 for bug 180132

You know pidgin? They have a very nice list (not dropdown) of all available profiles alone in one window. By double-clicking on one you can change its preferences. This could be accessible through the menu as "profiles...", another item could be "guest log-in" which opens a login window where nothing is saved.
At the moment I have no time at all but I can't get this issue out of my mind. The coccinella has just succeeded in grabbing my attention :)
