ability to move groupchat to sidebar

Thinking it would be nice to move groupchats to its own separate space, or to the sidebar with servers. 

I love my friends, but sometimes I really dont want their messages to be constantly pushing my dms down, or if I'm simply not in the mood to talk with that specific group of people. I don't want to close it, because that means I'll be leaving the groupchat. But I'm so particular about how my interface is functioning, it bothers me that I am stuck with a chat tab I can't ... do anything with, if that makes sense.
