I've covered Winhanced quite a few times at this point, most recently when it added achievement support to the launcher UI for Steam, Xbox, and even PlayStation games. If you haven't heard of it, Winhanced is a complete replacement for Xbox Mode on Windows handhelds, acting as a unified launcher for your library across various digital stores, all in one easy-to-navigate interface.
Now, its feature set is expanding once again, bringing with it my most requested addition: a built-in store browser. Honestly, it's something I wasn't even sure was possible, but it's now available in testing for users supporting the project.
