There won't be an edit mode anymore (meaning there won't be a separate editor screen). It's not going to change display modes on you when you go to make annotations. It's just going to let you annotate directly on the pages you are viewing. You will be able to zoom in to either one of the pages in two page mode, annotate, zoom back out and then continue.

This is going to help a lot, but how is the zooming going to work in dual page view, is the zoomed portion will still be in that previous part of the screen, leaving the other page normal? I was hoping in a way to use a pedal or touch action to switch back and forth between single half-page (full screen widht for annotations) to dual page (full size viewing) if possible, that would allow to write directly in the music without having to zoom, and go back to reading mode while saving on the way out!
