Show HN: Coordinates on Each Lichess Board Square (Chrome Extension) (chromewebstore.google.com)

I really want to learn the board coordinates, but:

- Training is boring

- Voice commands (probably best way) is slow and unreliable, for now

I thought of an approach of always showing coordinates and went looking, but found only a surprisingly large number of requests, a broken Chrome extension, and what appears to be a recent implementation of this feature for the "chessground" [0], which doesn't seem to be integrated into Lichess proper.

So I assisted ChatGPT 4o in putting together a Chrome extension that does this - posting here in case anyone else is interested.
