I downloaded version 2.06b and saw that you implemented 2 pages on one, so thank you a lot. But when I tested a pdf I saw that the zoom function doesn't work properly. When I zoom on pages in my pdf changes to other pages. For example when I have page nr 2-3 and I zoom in I see pages 3-4. When I zoom out I see pages 2-3. Moreover it looks better if when we display two pages on the screen they are stuck together without any gap. You could also create a method where the user can decide how many pages should be scrolled when the user wants to scroll in horizontal view. For example when we display two pages as one (pages 1-2) and want to scroll to next page (3-4, because we saw page 1-2) the user should have that option. Now we see pages 1-2 and when we scroll we see page 2-3. That feature would be very usefull. What do you think about it?
