Since Nexus Mod Manager for Linux fizzled out, I was excited to find a decent mod manager. It has built-in support for about 100 games, but adding other games seems pretty easy. I pasted in the Steam ID and path the the .exe of a proton game (MineMogul), and then everything just worked.
Yeah, I saw Claude in the contributors box, not super excited about that, but so far it’s worked flawlessly for me, so hopefully it’s not too sloppy…I’ll come back and reply here if I start encountering broken-arse garbage.
