It's the return of the chat prompter!

What's this white box on the control bar?
Now it says "type to chat" right in there when empty and unfocused.
My life is empty and unfocused, checking this in at 11:15 on friday night.
Things like this were tried in the past, and were always screwing up
and getting in the way of chatting or using the room. This is a skin,
not actual text, so it's more fuckup-proof.
