Just realized that a timeout is not a timeout

Playing an one-hour game with six minutes left and the opponent was at zero.
The game continued with me - well - not watching the game any longer with full concentration, just waiting for the opponent to time out. Finally, I lost by a sudden checkmate which was to be avoided easily by playing a little more defensive.

My feature request is more a question:
Isnt it possible to make a better and more exact programming in order to play games with clear and exact rules?
