Most users have multiple monitors these days. I keep RC open on one of my screens and woudl like to keep the most recent chat open while I work on other things. While I'm on another monitor working on something else, chats are coming in and I'm not being alerted if I leave the same chat active. As a result I've been in the habit of clicking a mostly unused team JUST SO I don't miss messages in the chats I really need to be a part of. We tested a competitor product some time ago and they kept the messages unread until you clicked in the window. This would be helpful for RC to duplicate, IMO.
