BoilR allows you to add all your games to your Steam Library, including art so that you do not have to leave Steam Library to launch a game, allowing you to use Steam essentially as an overall game manager.

To get started, first, download the EXE file and run it. If you have a Steam Deck, right-click and mark it "executable" under properties.

Then click "Import Games."

After import, restart Steam, and then you will see your new shortcuts added to your manager.
