Bookmarking already bookmarked rooms
When you are in a room that you have in autojoin and press Ctrl-B, you get a message that the bookmark was successfully added. When you press Ctrl-B, you get a message that it's already in the bookmarks. Looking at the bookmark managers, it's twice there then, the autojoin you had before and the bookmark which gave a success message. The button, however, is not shown, like expected. It's just the keyboard shortcut Ctrl-B.
