It would be great if the review online interface had the option to view the project as spreads or as single pages.

My coworkers who review prefer to make notes/revisions as single pages, but the publications I create are designed as spreads. It's a pain to go through and share as single pages and then move them back to spreads as I work. It would save me from exporting extra PDF samples to show full layouts when there is so much back and forth.
