It would be really useful to be able to customise what information is exported when you print/export PDF annotations. Specifically, for me, the ability to get rid of the annotation author, date and time would be useful as it is superfluous when I am simply annotating a PDF by myself rather than collaborating.
Also the ability to export into a .doc file (or a google doc) would be appreciated - the text export is useful but this does not include screengrabs in it. My workflow involves collating my notes on a series of PDFs into one word document to review, and I am finding it difficult to make this work smoothly with Paperpile despite being quite impressed with the product overall.
