Sorry for the confusion. While the iOS follows the orientation, it doesnt change how it rescales the page. For example, while reading in portrait, the default zoom places the full page on the screen. When rotated to landscape, the same logic is applied resulting in a tiny page in the middle of the screen surrounding by tons of wasted horizontal space. I would want the zoom to change to fill the screen horizontally (and of course, loose the bottom of the page). Plus a menu to easily switch between some of these zoom options, without always having to manually try to zoom in/out.
