Best of the best

This version of Dantes work really is wonderful. Of all in the app store its the best one out there. It not only gives you the entire readings, but images in a 3D viewing and also a full 3D model of Dantes visions of hell, purgatory and heaven.
Only thing Im having an issue with is how to navigate threw that 3D model. I can tap it to enlarge it or shirk it down to its original size. But when I have it enlarged and want to move up or down its not that simple, itll either rotate the image or at times kick me out to the main menu. Not sure if Im doing something wrong or if theres a glitch with it. Please fix if there is, or if its me maybe Im not doing it right and so then it would be nice to have some sort of side instructions on how to navigate threw it for a more easier time. Or a better way to scroll up or down the 3D model. Over all its an very great app and worth every penny for me!
