    If there was a way to have the app preload upcoming pages so they didn't appear pixelated during infinite scrolling it would be 5/5.

    Never thought the app itself has so many settings just to ease the viewer's individual preference, impressive!

    User friendly interface and functionality, however, the application seems to detect the rotation of the screen, that even if you locked the auto rotation it still rotates, hope this will be fixed this app is really cool!
