Comment 2 for bug 528964

I will post a screenshot next time I get the chance. The button is only there when a scheduled chatroom session is active, so I'll have to wait for that.

It does look basically the same as the Nautilus location bar, but the location bar doesn't behave like a single on/off toggle, since only clicking a different button (directory) will deactivate the active one. In Lernid, it is activated pressing it once and deactivated by pressing it again. So in Nautilus it's not a problem, since you have to move the mouse away anyway to activate a different directory (and since one of the directory buttons is always active). But for a simple on/off toggle, it becomes confusing.
