I figured I'd pass this along since I'm loving it. It's called Playnite, its an open source game library / launcher. Its really nice for people with large librarys from multiple sources. You can import GOG, Steam, Uplay, Blizzard, Origin, Windows Store, UWP, Physical Disks, & Emulators and launch them all from one place. Playnite also grabs the games wiki info, and provides metadata on the games. The Dev has a discord channel (see main page for link), and is helpful answering questions as well.
