For example Steam:

Maybe there would be a way to recognize this situation and integrate with nixos-conf-editor to have one button to edit it there.

I have considered showing something along these lines, however, currently, there isn't a good way to figure out exactly which packages are installed by which options other than evaluating all of nixpkgs. I've seen that nix-store --query --requisites /run/current-system shows all derivations, but there isn't always a 1-1 match from derivation to attribute, so it would be as unreliable as nix-env. It could probably be done manually in the future though

I think maintaining the matching manually is too unreliable, because it will easily get out-of-date.

Could we or Nix cache the result and have to evaluate nixpkgs only once? I think they do that for available packages, so it should be possible to do it with options as well.

Yeah that could be done, not sure how to do it though since that information doesn't seem to be in the evaluated options
