I design large catalogs that need to be proofed by 40+ reviewers. Individual reviewers need to be able to print out their pages as 8.5x11, but the supervisors need to be able to view the document as 2 page spreads so they can see how the document visually flows. This isn't an option when I send them proofs using Share. Share only permits single page view. Outputting a separate proof as a spread is a cumbersome workaround. The proofers should have options on whether they view Shared pdfs as Single Page View or Two Page View.
