ANONYMOUS I think it would be good to include a 'select sudoku' button to be able to re-attempt sudokus that you previously had difficulty solving. (Version 1.1)
MARK LOHREY Great widget and update makes some great improvements. On my wish list would be the ability to add different colours so if you get to the 'guessing' stage of hard puzzles you know where to go back to when it goes pear shaped! (Version 1.1)
JAKNUDSEN Would love to have a 'clear this Sudoku' button, and the ability to type with the numpad. Otherwise, great! A bit more compact size would also be beneficial (Version 1.1)
