Create A Spectator Room.

I want to share a feature idea. At times i want to watch the games my friend are playing but because they are in a serious/competitive game they would self isolate into a limited talk channel eg. 3/3. This is obviously to avoid others from coming in to the channel and distract them from the game. Hence, wouldnt it be cool if there was a spectator room. Where we could watch their share screen games but without bothering them but we in the other room are still able to converse but watch their game. I hope it is understandable what im trying to say.
