@Finlip It's done! You can change the setting at lidraughts.org/account/preferences/game-display

If you change the 'Board coordinates' setting to 'Inside the board', you'll see the coordinates in each square (after you refresh the board).

If you prefer to see the coordinates at the edge of the board only, just leave it at 'Outside the board'

Thank you!! :-)

I've already been waiting at that option even before suggesting this feature. I feel quite proud about it. :)
