Seems to do everything that I want to do just fine. PDF files imported from iTunes work great and I can turn pages with my AirTurn pedal just fine (selling point for me).
The only request i would have, is that you give the user the option to get rid of the lame page turn animation. Im sure the developers are quite happy with it, but I find it to be tacky and annoying when I am using it. My PDF files are white text on black background to be more pleasant on the eyes on a dark stage and the white flash that is generated when pages turn is a big turn off.
