I have some suggestions to improve RC2.
First, is that when you're typing in the server list, trying to find a specific server, you will notice that as you type the selection in the list changes according to your input. When you have stopped typing, and it's resting on you final selection... it would be nice to be able to press "enter" and have it log into that server.
Secondly, I would like to see a "/me" command added to the chat. I realize it could be used and misused, as I examplify in my picture (

) but I think it could be handy.
