I love the whole setup. My only request would be to allow turning off the "possibles" display. Sometimes, I like to try to do that scanning myself.

The new features are great...
But the "difficulty" button looks strange... It does not match the graphic style.

Thanks this widget is great. A minimize button would be cool too.

Great widget! But that undo function just isn't enough. It will be way better to change a selected number by holding CTRL and clicking it, for example, and making it again a candidate (on that row and column). This is the only thing that's keeping me from using your widget, and I would really want to use your widget :). Oh, and i would love some statistics, like average time (on easy, hard, etc), or number of sudoku's played, or clicks clicked :).

Your wish is my command.
