Hi Kris,
feature suggestion: could you, please, also introduce
three-finger-swipe to the app? I'm currently using the two-finger-swipe to turn 5 pages, but I also like the idea of "smart-snapping" (browse by chapters/bookmarks).
Thank you for considering this. It works great for video apps like AVPlayerHD or VLC Streamer: two-finger-swipe = jump by 10 seconds, three-finger-swipe = jump by 30 seconds, etc. Marvin gestures might accomplish similar things, just for books, not movies.
