The revamped Xbox app on PC has introduced an 'aggregated gaming library' feature, allowing users to manage all their installed games from a single interface. This feature is currently available for Xbox Insiders and supports various platforms, including Xbox, Game Pass, Battle.net, and other leading PC storefronts. The app will display games from supported storefronts under the My Library and Most Recent sections. Users can customize their experience by disabling the feature or hiding games from specific stores. The feature is set to debut this holiday season on the ROG Xbox Ally and ROG Xbox Ally X, with plans for Microsoft to expand support for additional PC storefronts over time.
