Very minor suggestion here, but in the Report window, the Critical Hit checkbox one has selected in Options does not show up in the Report. For example:
252 Adamant Quick Claw Rhydon Stone Edge
vs. 252/4 Bold Mesprit : 88.2% - 104.3%
This is a CH. Pretty self-explanatory and I'm sure incredibly minor effort will need to be expended on your part.
