Replying to Possibility of bringing the quick chat back?

is it possible to bring the quick chat back that used to be on the right side bar? What if there was a thing like on facebook how it can pop out from the side if your browser window is big enough. What I'm thinking though is that if someones on a computer they could have access to the quick chat on the side of all the online users or something.

I don't know whether this is a good idea or if it's even possible, I just remembered the quick chat and thought it might be neat to bring back.
