Please check the "File" menu. We IMHO should be consistent in the whole app... - We could replace "Open library" again with "Open file". However, "file" does not work with Medline/... -- does your drop work with Medline (auto import 😍), then "file" is OK for me! Tobias Diez <[email protected]> schrieb am Fr., 13. Sep. 2019, 23:35:

In the end, I prefer "open files" since it makes the action clearer for the user: she drops files into JabRef where they end up as new libraries. — You are receiving this because you commented.
