yea i tried to do this (somewhat successfully) with a custom editor for css https://github.com/feralsoft/charisma (demos on my old x https://x.com/charisma_css)

css is primed for this since you can write your rules in such a way that rule order doesn't matter, which means you really don't have to think about where your code it

in my dream world, i have very smart search (probably llms will help), i look at just the minimal amount of code (ideally on a canvas), edit it and remove it from my context

i don't care where or how the code is stored, let the editor figure it out and just give me really good search and debuggers

I care, because I don't want any vendor lock-in. "The unreasonable effectiveness of plain text" hasn't gone anywhere.
