The autofill is nice but you can't edit it so if your character has a feat or ability that increases a modifier you have to capture it somewhere else. Specifically this applied to initiative with the alertness feat. Also there is no place for keeping track of XP. I do like the fact that the attack fields expand to allow to type in even lengthy damage modifiers and types. Also the Expertise toggle is a really nice feature.

I have chosen however to not use this product because the two negatives outweighed the benefits in my case.
