First off I want to say how much I enjoy the update and how much of an improvement this is over the old CotG Desktop and thank you!
MMA - Maybe add a way to add MMA characters without needing to use card notes for the MMA charts and Offense and Defense stats.
I like to make bootlegs on this but don't have an easy way to print off, or share my creations. - Make a way to print off the stats, or convert them to BBC code.
The Note function didn't really work in the last one, but I like the idea of being able to record the moves as it makes it easier to pick up a match where you left off if you get interrupted.
The dice counter was nice too in the old version.
Like I said this version is great and I look forward to seeing other versions or updates!
