Due to a suggestion in a review, I have implemented into the controls the ability to rotate pieces using your Right Mouse button, as well as the scroll wheel. You can now choose whichever is easiest for you.
I have also fixed the 'Completed Puzzles' section, and put in an 'Uncompleted Puzzles' tab as well, due to another suggestion.
Minor bug fixes. Menus look nicer, and the place-settings for pieces are transparent and larger.
Enjoy dears!
