Please consider adding controls to make the compare mode full screen size (instead of small modal size) so it is easier to view the changes. Currently even though I use a large monitor it is annoying to only be able to use about 1/4 of my screen to compare changes, which makes me have to zoom in a lot.
It would be great if we could make the review mode full screen to really see pages side by size without having to zoom in manually always. Or use a mode similar to comments where you are able to navigate to the next change in context, but with some visual indication that this is a change for review.
