Great app but needs some work - PLEASE!

This is a wonderful little app, we love it. However, a few features of ChessWise should be adapted: 1) variable engine strength 2) save/load PGN 3) email game (maybe even auto-email so I could get my daughters games automatically, like on ICC :-))
Can you work on it a little bit more please?

Update 2/9/13:
Now the engine strength can be set, which is great and it deserves five stars.
Can I suggest two more features (on top of email/save pgn) that would be easy to program: Count the number of flashes and the number of illegal moves. These would provide good feedback on ones progress.
