This is something that might be far in the future, but I hope that if I suggest it there is a possibility that it will come true. I find myself searching for articles found in the bibliography of the article that I just finished reading. My suggestion would be for Endnote to recognize bibliography/reference sections in the PDF articles currently in my library and then search for the ones that I click on, so I would be able to download their PDFs (or jump to them if already in my library) and continue my reading/research. Are there any other researchers that this would be useful for? Also, is it feasible?
