You can actually search this list in-client also, which is pretty cool. Super handy for stuff like Blizzard games, MTG Arena, etc

You still can add previously installed games (Steam, etc) too

No other software store puts a focus on libre games like Athenaeum.

As for GZDoom I believe it is libre, even if it's just the engine. If that's incorrect feel free to open an issue on gitlab and it can be marked as NonFreeAssets or removed if it had nonfree source code.
