I have been unable to set up a good system to store, read and annotate pdf files (scientific articles) in Evernote. The workflow I have in mind would go like this.... 1) Find pdf on web, and clip to Evernote (this works fine). 2) Open article on iPad, read and annotate in third-party app. I use Goodreader, but I could try another. 3) Save annotated pdf back to Evernote. Any method I have tried up to now does not save my annotations back to the Evernote version. Thanks. PS. As an aside, what is the best way to get a pdf attachment in Gmail into Evernote? In the new Gmail format, the clipper doesn't work on the default Gmail display of pdf attachments. I can download it and drag it in, of course, but it would be nice to do it without leaving a copy in my download directory.
