EndNote seems like a great place to store documents, but it is not a great place to retrieve documents. The ability to export a selection of PDF files (or export groups) would be useful for collaboration with people who do not use EndNote, as well as maintaining libraries of PDF files outside of EndNote.
Annotations alone are not especially useful for collaboration.
Similarly, the directory names for PDFs managed by the database are just a series of numbers. This makes it impractical for browsing the directories using a file manager. Can this be changed, for example an option to create user friendly dircetories.
Endnote already has functionality to create user friendly and updated PDF file names, bu tthis is worthless without exporting of those files or human browsable directories to find the files in.
