Could you add swipe left/right to go to next/previous chapters? Thanks

It is in the latest version that was uploaded to Apple, see the post dated 12/28/08:

Swiping to the right is pretty jerky and to the left even more so. In fact swiping left doesn't work most of the time.

I'll look elsewhere on the forum for something on this.

In version 4.x it is much improved over 3.x, in fact very responsive going forward (to the right) or backwards (to the left).

I can confirm the fact that swiping left to right is awesome in 4.0!

This is not working on my iPad. Is this a known issue?

We no longer support swiping to go between chapters. You can change chapters 3 other ways, though: right/left arrows at the top, the slider in the lower left, or by tapping the book or chapter number at the top.
