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 have a small request for Knight Fight: to show the values of the previous moves instead of just the locations. So in the game notation on the right, instead of saying "j4", it would say something like "j4 (76)". Or in the case of doubles it would say something like "j4/d7 (55/88)".
The way it is, I find myself going back to previous moves a lot to see exactly what just happened. It's a little disorienting, especially when you're playing many Knight Fight games at once!
Just adding information about the last move would be good, too, if you don't want to change the notation of the whole game.
