Ive downloaded all the comic viewers in the app store. Sidebooks CLEARLY has the best features behind-the-scenes.
Its non-destructive, can create folders, sub folders for all your books etc.
BUT it needs more stability turning from Portrait to Landscape... And by more, I actually mean ANY stability. Crashes like 90% of the time.
Until SideBooks can fix, BookmanPro (while not pretty whatsoever) has equal filing guts, and ~100%-stable viewing UI.
