It would be nice if we could join queues for multiplayer games from the “Play” tab. The current system from the Hub is great, but it would be one queue for everyone. In the best case we could also see how many people are currently queued up for the game.
Another idea is to show for games under the “Active” Tab how many people are currently playing it. I personally would be much more likely to join a game with 7 players, than a game with only 1 player.
