I understand the Navigator tab, but it seems small. It would be nice to have something like Photoshop Elements. One can "Arrange Documents" > select "New Window," and then select "Two up." This lets one view the same picture side by side, allowing the person to work on one picture and see the full picture next to it. This is especially helpful when one is zooming in on their work and the picture next to it is zoomed out all of the way.
