The Xbox app for Windows 10 has gotten a massive update. Major Nelson has all the details on the new features, which includes improved friends lists and the ability to use your app to write things for Xbox One instead of the tedious controller typing.
Here is the full list of everything new:
Real-time Friends: Friends list will automatically refresh with your friends' on/offline status and the apps and games in which they're currently engaged - including whether the game they're playing can be joined via multiplayer or party.
Real-time Activity Feed: The need to refresh Activity Feed items is no more. Keep the Xbox app open and your Activity Feed will let you know when there are new items to view, comment on, like, or re-share.
Game progress comparison: Discover how you stack up against your friends on specific game progress by visiting the Achievements section of your profile and selecting 'Compare.' You'll enjoy a side-by-side comparison of your selected friends' progress on games you've recently played, including game completion percentage, Gamerscore and Achievements earned.
Console text entry: One of the most requested features from Xbox Feedback to the Xbox app on Windows 10 - the ability to use the Xbox app for text input on Xbox One. You will now be able to use the Xbox app and other inputs compatible with Windows devices - keyboards, touch keypads, and the like - to enter text in search boxes and more on Xbox One.
