It is a real problem, I've seen heated discussions in a few companies, and it can take out a big part of the fun you have in your work.

We really need to write an editor plugin/solution for this. Your editor should show the code in your preferred style, but saving it in the team's agreed style. And then a local-style.js for your own settings, and a team-style.js for the team settings. local-style.js in the .gitignore. Should be possible though?

It'd be possible but it's a non-trivial amount of work: think about things like linting or debuggers where line numbers might vary substantially, sequencing things in tools around merges and code review, etc.

The option you can do right now is to use something like Prettier where everyone's experience is entirely consistent and you have no cognitive load switching styles or dealing with inconsistency. This is basically free and means that there's a whole slew of high-emotion discussions which you can stop having for the rest of your career, in favor of working on things which actually matter. The older I get, the more that looks like pure win.

You could absolutely make that. It sounds neat.
