It would be beneficial to be able to observe the page's boundaries when you zoom in and pan to them. I appreciate the ability to observe the "shadow" of the page's sides when zoomed out, and I would like to be able to do the same when zoomed in. I would appreciate a visible border that is either 1/4" off the page or user-definable, rather than having to navigate the page halfway off my screen.
