Dear John,
I upgraded org-ref to get org-ref 3 and I met the following difficulties: - my shortcut to get the list of my bib file did not work, and I have to use the emacs menu, - I did not get via org-ref a pdf file of any paper, - cite links with the page(s) via "description" show only the page but the reference is hidden, at the moment, I downgraded to org-ref 2 and everything works fine. I imagine that all is in the documentation you wrote to solve these problems, but I wanted to point out them, in order to solve them easily and to contribute to the improvement of this terrific tool you gave to us. I do not imagine now writing without org-ref. Thanks ! Jo.
