Auto-Collapse Folders That Aren't for the Bookmark

When I bookmark a channel, and then go back and join on that channel, it would be great if that were the only channel that was expanded.

Playing on a multi-monitor set-up with a game playing full screen, it would be great if, when I join on a bookmark to a specific channel, that were the ONLY channel/folder open. That way, when people in that channel speak, I won’t have to scroll to get the active channel viewable.
