I made a new release with the css modified to somehow fix the original problem with showMoves=auto, moves were not showing at the bottom in small screens as intended.
Now they show down, although with fixed size at the moment, but I think is usable. Please give it a try.
It is indeed usable now. I’d prefer slightly smaller prev/next move buttons to save a bit of additional space for move area maybe, but this is rather a voiced caprice than an UI improvement suggestion.
Can’t wait until it’ll be at least able to display FEN strings (maybe by narrowing down the buttons a bit you could squeeze just enough screen space between the board and the buttons to display the FEN string of the current position).
