Microsoft have just detailed what will be featured in their October Xbox One update. Members of the early preview system should be able to download it now.
Snap Updates – We’ve updated the Snap Center to include quick access to many of the things our fans wanted faster access to when playing a game – Friends, Messages, Game DVR, clock, and battery indicator – as well as making it easier to close and open new snap apps when playing a game. A double tap of the Xbox button on your controller will bring up a menu that allows you to open a new app in snap mode, close the current snapped app, or switch focus between your game and your running snapped app. Additionally, two apps have been optimized for Snap mode:
Friends Snap App – Access your friends list without leaving the game. Quickly check your friends list to see who’s online right now and take actions like send message, invite or join.
Messages Snap App – You’ll be able to open, read and respond to messages in Snap mode, and messages will now be displayed in a threaded conversation view.
