For the use in especially iPads:
I asked the forum if this feature existed in DPS and was surprised to learn that it didn't. As it is now the viewer (when saying 'viewer' I mean the user/consumer of the iPad) always lands on the previously viewed page in the article when swiping horizontally back and forth.
I believe that having the ability to have the viewer always land on the top page of the article is a feature that would enhance the ease of use from the viewers perspective. E.g. when scrolling (horizontally) back to an article and then landing on a 'navigation' page that has hyperlinks/buttons to underlying pages instead of landing on the previously viewed page if you scrolled down (vertically).
