[Suggestion] - Want to play XXX signalling and group chat

[Vio]

Right now on steam there is an indicator next to games if you have friends in a given game. I was thinking it would be great if steam had a similar signal where a friend can indicate that he's getting ready to or wants to play a specific game. I.e. you right click the game and mark yourself as "want to play" the game - limited to 1 game at a time. Then on your friend's games list indicate that someone on your friends list wants to play said game right now.

This feature could be expanded with a 'create want to play' group chat for the given game where you can organise everyone and get in the game.
