I would like to be able to keep all of the cited references within a document inside of a single folder in the app (to more easily keep track of references that have been used in a given paper). I can do this one by one- move a reference to a folder before/after I cite it, but I would love to know if there is a way to more easily keep track of what citations are in a document from the Paperpile app. Maybe somebody has figured out a workflow that I haven’t? Thanks!
