Thanks for your other tips as well. I'll try and approach it that way, just doing it little by little, I don't always need VSCode and for simple edits its already way better than nano, although tbf I didn't take the time to learn all of nanos functionality.
It probably is best to take it slow and not cut corners. Play some vimgolf and take it slow, try to get the base stuff like regex search and replace down. Learning regex well can be applied to other things as well, so it is worth it to practice it in the context of vim.
