Can delay for up to like a year, but generally I’ve found it to be fairly painless. I definitely do it via the CLI because it’s easier to see warnings. It will block you if anything you have installed has issues (often fixed by waiting). Just follow the docs

Been doing it for years :)

My two cents would be to use thicker traces, in this application using the thin traces doesn’t help, and can make them easier to break. I would personally add ground fills on top and bottom out of habit mostly though, not sure if it would help in this situation.

Also use the silkscreen, it’s free (effectively) so put labels on connections and also you can import images into it if you want (enjoy it).

(Note I’m on mobile so can’t inspect the kicad but will if I remember later)

Edit: sorry didn’t see flood fills I’m image. Ignore that 😅
