Your Xbox Live friends list on will live inside its own app on Xbox One, simply called Friends, and Microsoft's Major Nelson demonstrated the features of the app in a walkthrough video released today.
Major Nelson showed off features including the profile page; the friends list itself, which allows you to "favorite" users; one-way "following" of users; and the activity feed, which gives you a Twitter-like up-to-the-minute list of what your Xbox Live friends are doing. The activity feed can be used in Snap mode with a voice command.
Check out the full video above. Microsoft also released a video featuring interviews with company employees discussing the multiplayer features of Xbox One; you can watch it below.
