Do you miss something on BrainKing.com and would you like to see it here? Post your request into this board! If there is a more specific board for the request, (i.e. game rule changes etc) then it should be posted and discussed on that specific board.
I assume this would be quite difficult to add (could be wrong), but what about in Chess, Checkers, Tank Battle, Tablut, etc, when the piece you click on has only one legal move that the move be done and you are taken right to the "submit?" screen, rather then having to click the destination square as well. It does that on IYT, and seems to be quite useful :-)
