A small suggestion: would it be possible for a spectator to be able to flip the colour so they can visualize the game a little differently? Right now if the game master has taken black, the spectator will also see the board from the black side's view. Maybe the letter H could work for the same.
Hello. This is already possible. To do this, use the number keys and the board will switch accordingly. This needs to be added to the f1 help message. It is in French, but not in English.
