Can’t speak for everyone, but 1,2 aren’t operations that I do hundreds of times a day even remotely. Otoh, I can see the difference^ in scrolling highlighted text between my 6600 and 8700 boxes in vim (which is my main tool; tried and ditched vscode for many reasons but speed, which is fine at both boxes). Maybe I could see that if I looked for it, but it’s not of any import.

^ not just slower, vim annoyingly skips scroll events if they arrive too fast. My system is configured for 6-7 lines per WM_SCROLL, and I guess that adds to the problem. As a result I have to scroll slower (at 6600 box) for vim to scroll faster.

On editors in general: I’d like to have an editor as a library for which I could create modes/cli/behaviors myself. I believe that the sharpest tool is the one you sharpened yourself and for basic editing there is notepad2 and alikes. Vscode is much closer to that, but it’s too cumbersome to create/update personal extensions, so dumb vim hacks be it.
