It tends to break when you force power off the machine in my experience, where ext4 is super resilient to that kind of stuff.

Thats my experience at least.

So add your user to the new docker group made on install of that package and you’ll be able to docker without sudo. You may need to relogin or newgrp docker before it works tho

Anything that’s steam workshop should just work for the most part.

There’s also steam tinker launcher which you can use as a shim between steam and your proton in order to hook modloaders like modorganizer for Skyrim.

Anything that’s “drag and drop” should also work seamlessly.

Worst case scenario you can add your mod organizer as a non-steam game and browse to your game folder in the mod tool.
