I would like the feature that I could play my aponents moves and then my own and submit these moves to the server so if my apponent plays what I thought they would already know what move I want to make so my aponent does not have to wait for me to make that move. This is not like auto pass because I am still chosing what move I want to make I just can chose before hand.

Would be very usefull in games like anti-chess and line 4 were there are often times were there is only one good(or allowed) move for your oponent.
