When you hit page up or page down in an Acrobat PDF at 100% each page is centered and in the exact same position. Same thing when using the scroll wheel.
If I am working with a book that has a lot of pages and want to go through the book quickly and look at the spreads, when I use page up or page down, the page rapidly becomes off-centered.
Making this work as efficiently as a PDF file would be tremendous.
