I have a 3-page PDF. I need to view pages 2 and 3 together on the same screen. It can't be done in Acrobat. I suspect this is a problem any time you need to have the even-numbered page on the left and the odd-numbered page on the right. Not to mention that even finding the page view settings is almost impossible with the current UI.

Did you ever think that maybe you should run this stuff by a focus group before deciding it's a good idea?
