Xbox One Preview Program members can now download a new version of the update containing more features than before. As explained by Xbox engineer Mike Ybarra, the update to the update introduces the new Gamerscore leaderboard, a Sports section for the OneGuide, and the ability to move pins.
Ybarra also provided some instructions for how to move your pins/apps around. "Highlight a pinned item and hit Y, or press Menu, then select Move," he said.
You can see this in action right here.
The Xbox One system update that introduces this feature and others should arrive for everyone "in a few weeks," which would be sometime around early February. Check out this post for lots more on what's included with the new Xbox One update.
Before this, the latest Xbox One system update was the New Xbox One Experience. It arrived in November and totally overhauled the Xbox One's UI and introduced backward compatibility support for Xbox 360 games.
