One thing I would like to see is the ability to move fielders and baserunners on custom fields so they line up correctly.

Also I hope to see in Version 10 the ability to steal with 2 strikes, and on every steal attempt, have the option of the batter to swing away, or take the pitch.

One thing that bugs me is the high percentage of batters with zero homers hitting homers. For me personally, it's a replay killer when Duane Kuiper hits 3-6 homers in a season. I know there is some who like that 'what if' feature, but maybe have an option for zero homerun batters, and pictures. That would satisfy everybody.
