It would be extremely helpful to have the ability to download a PDF (or image, or other file types) with comments included. Alternatively, could there be a way save out just the comments as it's own ...
Another vote for this idea. My clients add comments which are then 'trapped' on dropbox, no way to get them out. We need to be able to export comments, ideally both as a separate file AND embedded in the PDF like regular PDF comments. The latter is important for then merging with other PDF comments into a master file.
