Can be set the ‘undo’ button to a different color than ‘send move’ button?
That’s probably a good idea, will do for this next patch
May the button ‘accept undo’ when the opponet ask it to you can be change the color too?
Hmm actually the undo request should “halt” the game play. It’s way too easy to miss even the different colour undo button when doing simultaneous correspondence clicking. KGS has a popup. Something that forces people to click “accept undo” or “do not accept undo” would be good.
