I love it! Bot I have two buts (or rather ifs).

Is it possible to make the program calculate with the free spaces aswell as the free slots (it's often possible to move more than five cards, but now you have to do it manually in two or more steps).

I would LOVE to see a highscore-function. Maybe on time, but definately a track record for won - lost games. I like to get a graphic view of my obsession from time to time...
