Add me to the list of people requesting this. I take notes on my ipad with a stylus, and on paper, often on the same topic. In the past I have scanned my paper notes and inserted them into the ipad notebook (using Notability). That way I have a consolidated set of notes on a topic in whatever form they were originally created. I appears that Penultimate lets you export pdfs, but not import them. This is the principal reason I am still using Notability and not Penultimate.
