Tbh I think if someone is trying to do this, they should just use the native app. Even if the OGS header is removed, and the arrows are moved, the browser header takes up a lot of space.
FWIW, I checked shinkgs and gokibitz. In comparison, OGS does pretty well
I agree. The thing is to aim to the same quality as what apps offer (not web). Checked that kgs app which has similar well fitted goban as the apps we mentioned already. I checked more, golinks, Goquest… they all are.
Ok for a bit of optimism, i put a lichess screenshot with perfectly fitted chessboard. There is still something on the web side with similar size to aim for
