I am having lots of people reviewing page-oriented instead of spread-oriented documents. (Books, manuals and the like.) Some are asking why they can't view the PDF in Share for Review as a single scrolling page, like in Adobe Reader. I personally don't care, but I have no answer for them. It would be nice, and it seems it would be technically not that difficult, to support single-page view. This would really help people reviewing on a tablet or a phone.
