Yay! It seems they now re-enabled the center button functionality. Now you can access the Steam menu when you're playing a CloudLift game by pressing the center button on your controller. This is great as now you can chat with your Steam friends and also take screenshots (something I hope the Xbox One adds in a future update). Just make sure to upload them to the Steam Cloud if you want to keep them otherwise they will be removed after you exit the game. All of the following screenshots were taken on my TV using the OnLive Game Console. It feels a bit weird seeing the Steam interface on my TV but it's a welcome addition!
