Xbox Wire has details on a new version of the Xbox PC App rolling out to Xbox Insiders. This will go into wider release this holiday season when it comes to the ROG Xbox Rally X handheld system. What's new is how it will consolidate your gaming library. Word is this will encompass Xbox, Battle.net, and Game Pass, with support for additional PC storefronts promised:

With the aggregated gaming library, players can conveniently launch games from Xbox, Game Pass, Battle.net and other leading PC storefronts from a single library within the Xbox PC app. Whether you’re on a Windows PC or a handheld device, your Xbox library, hundreds of Game Pass titles, and all your installed games from leading PC storefronts will now be at your fingertips.

When a player installs a game from a supported PC storefront, it will automatically appear in “My library” within the Xbox PC app, as well as the “Most recent” list of titles in the sidebar—making it easier than ever to jump back into your games.

And this is just the beginning. We’ll continue rolling out support for additional PC storefronts over time.
