Well one thing I've complained about before regarding the otherwise decent PDF Reader is the fact that the app does not automatically navigate to the next/previous page. It seems that the only way to "turn" pages is to use the menu, which is asinine. Every other PDF reader I've ever used knows that when I attempt to scroll past the current page's borders, I want to navigate to the next or previous page.

This completely kills its usability. I expect text reader apps to employ easy one handed operation, and the PDF Reader fails miserably in this regard.
