I haven’t used the feature yet, but I assume the Steam integration imports your collection to your"steam" shelf.
It would be nice to have this implemented for others stores like Epic Games, GOG, Amazon Prime Gaming, etc. so that those shelves don’t have to be updated manually.
Oftentimes, I’m interested in a game and don’t realize I already have access to it.
That would be nice. No one else has official APIs that I can grab games from. My wish list in order would be Epic, GOG, Sony, Xbox, then anywhere else.
