At this point, when we export book with margin notes to PDF, when only have the option to Export Highlighted Pages, or Export All Pages. However, I'd really like a middle option, where MarginNote exports out all pages, but if there aren't any highlights/notes, that it would leave the PDF without a margin. It's just cleaner to the eye if the PDF page has no blank margin, leaving readers to wonder why is there is a big blank margin sitting there for no reason. (If we choose Export Highlighted Pages, then MarginNote skips the unhighlighted/unmarked PDFs, and that's not cool either, especially if you're reading a document that requires continuity between all the pages in between.) Thank you for your design!
