Also would be nice to have the option to listen to group IM's specifically from your active group. Of course you can turn it off, but sometimes I don't want to be bothered with IM's my other groups.
(as an aside, can we get external camera controls rather than having them linked explicity to alt-mouse/ctrl-mouse/ctrl-alt-mouse? And more window focus control... like assignable hot-keys and stickies.
)
