Maybe make it so that you can toggle through the chat tabs with, say, Ctrl+< / > or something like that. I bring this up because you can click stuff through the chat, which is actually great, because I don't have to close chat to move from song select to the main menu and stuff like that. Good example of when it's a bad thing though is how I and I'm sure a few others from in-game were accidentally clicking "Exit" through the #meeting tab during the community meeting. Being able to toggle through rooms you've entered with some key command would be really useful in some cases and reduce the risk of clicking something stupid by accident.
