Not going to lie, pretty good for readability. If they don't merge it maybe give VSCodium a go.

If the top left window actions can be one color each, then the bottom can too!

it makes me sad that vscode extension api is so specific and constrained that this has to be done as a change to the editor code itself

If you want that kind of features to be adopted, it's best to the maintainer's input before writing any code.

It's likely for them to want some features on top of what you did (I can think about styling for instance, in which case the name "rainbow" might not be super appropriate?)

(I didn't read the code, maybe you thought about that already)

At the same company that immediately backtracked on a an image of a guy wearing a green hat in an installer? Probably.

Real happenings, Zero Bullshit

NOTE: I have zero fucks to give about ether of those specific issues, I’m just pointing out Microsoft's spine for these things has the consistency of overcooked linguini
