After using iScore for half a dozen MLB games, a few thoughts:
1) On the scoring screen, bring up the pitcher's card when you touch a pitcher, the same as happens when you touch a batter on the lineup list;
2) On the scoring screen, prior to the first pitch for each batter display his slash line below the batter's name (where the BSF shows up)
3) On the scoring screen, on the scoreboard, for the active half inning display the runs number in a different color (as they do at Fenway)
