With the release of Windows 11, a new feature called Widgets appeared. Personally, I don't see it as very useful, but I still developed an app similar to the one I made for the Windows 10 Tiles.
Below I detail how it works:
Autodetection of Installed Games
Before adding a Widget, the app can automatically detect what games you have installed on your computer without having to do anything yourself.
Widgets Customization
Although the app will load default images of the game for the Widget, the user can change them to their liking or even modify which game the Widget will run.
