Twitch's Xbox One app just became much more useful if you can't stop watching live streams. Thanks to an update, Amazon's game-focused video service offers the Host Mode viewing you've seen on the web -- if a streamer wants to showcase someone else's work on their channel, you'll see it on your TV. Also, there's a fresh Recent Activity hub that shows channels you've watched, channels you follow, and recommended on-demand clips. All told, you're much more likely to have something to watch... even when your favorite "let's play" host calls it quits for the night.
