Pages laid out vertically

Currently, if a score has multiple pages, they are laid out horizontally, like Win8 startscreen items. For accessibility reasons explained below, it would be very nice to have ability to lay pages one under another like in word processor.

I'm working in such a magnification that single page is spread across the whole width of my screen. That means I can't see vertically the whole page, and if focus skips to new page but I'm not yet done with a previous one, it's quite a hassle to move score back to bottom of previous page, since both horizontal and vertical move is necessary. If pages were laid out vertically, this situation would be easily solved by a slight move of mouse wheel, bringing back into view the last system of previous page.

Why I'm talking about accessibility when no screen reader or Braille is involved? Since low vision also requires some adjustments for user being able to work comfortably.
