One problem I have with Mieru on the N9 is that, sometimes, I accidentally tap in the borders and move the comic backward or forward. For example when I'm changing the zoom level. Would it be possible to implement a next/previous page by swiping from the borders? This could be optional and keep the tapping feature (for those that prefer it) by default. When you are in full screen, you could disable global swiping in order to use the gestures for page changing, and re-enable it when showing the menu bar.
