When using writer with more that one page in view it now possible through the
zoom function it would make much more sense for pages to scroll horizontally. 

A primary advantage of seeing 2 pages is to see what is before or after a
particular page, but when one scrolls vertically this only occurs on every
second page because the page before the page on the left hand of the screen is
largely above what can be seen on the screen and the page after the page viewed
on the right of the screen is also largely out of view. 

It should be possible to move through the pages horizontally so that the user
can decide which 2 pages they want viable. This would be great when writing or
even formatting.
