You sound like me, you'd be better off learning computer science and making it yourself. I havent met a dev on earth besides me that likes to nerd out with extras like that. Maybe my friend Zap.
These guys do a much nicer job than most people on internals with that being said. Nobody makes autistic level shit like that. Like once I learn internal frameworks, I would make stuff like automatic cyclical no recoil that intelligently and dynamically changes, but thats just because coding makes me happy, and there isnt much else to do in a program besides think up weird shit
My pixel software has like 100 variables lol, its ridiculous, I highly recommend getting into coding, even if its just playing with some open source material, its very satisfying, albeit painful at times.
