Power play last the full length regardless if a player score. The period or game does not end before the player out of the box. That way you don't get a get out of jail free card because the clock stopped the game or the period and you don't get to ice the puck either. Another rule I change is the stupid automatic call for delay of game when the puck is thrown in the stand. Make it icing with the same consequence of not getting a change instead. And finally there is no such thing as "intent to blow" anymore. The play is live until a ref blow the electronic "whistle" that way we can get an accurate time stamp on when the play is really dead.
