Fun. Need ability to save Sudoku game and quick play timer-off mode to learn games

Ive had this app for about a week, and am enjoying it. I have received the Sudoku bonus game. I dont necessarily have time to finish a Sudoku puzzle in one sitting. It would be great to have an option to save a Sudoku game to my profile to finish later. Also, since some of the games are not so familiar to me, I would like the option to turn off the timer when doing a quick play of a game. That would let me study the game to learn how it works. For example, Id like more time to figure out the 3D aspects of Pipe Connection (how to make the pipes cross over each other to complete connections), but that darn timer keeps putting a big red X across the game! :-) Thanks.
