Snap Mode allows you to dedicate a portion of the screen to a single app, taking up a large column typically for viewing media apps like OneGuide's TV side-by-side with a game.

It's a throwback to Windows 8 apps, which could be snapped side-by-side in a similar way. Microsoft killed the feature for Xbox app developers last summer when it launched UWP for Xbox One. Xbox owners were still able to access legacy apps that made use of Snap Mode, but no longer, with the builds on the latest Xbox Insider Program update wave.

We reported last November that Microsoft was working on picture-in-picture functionality as a replacement for Snap Mode, and today, we've gotten a glimpse at what that could look like.
