I probably expressed myself unfavorably ( english is not my native language). I mean that I don’t have to create nodegroups. So the easiest thing would probably be to create something like a uber nodegroup (or more) with the options you need the most. Check out “Uber Compositor” or “enrich”. Your addon already has everything else. Architects and other client workers love ready-made presets. Then I would leave this version free and you can easily put the other one on gumroad and blendermarket for 10-15€.
