Adds keyboard shortcuts to change folder, move/copy messages, with folder name auto-completion (using only the keyboard). Same for tags. Also includes a system of rules to suggest a target folder for saving messages; re-creates Eudora's Alt-Click; facilitates navigation in the 3-pane window; makes it easy to change between To/Bcc/Cc fields in the composer; facilitates tag-oriented operations. All that with the keyboard only!
LocalCopy is a plugin that extends the popular reference manager JabRef. It provides an automatic download feature for preprints from the arXiv and journals that are linked using the DOI-system or that specify an URL link.
