Direct Paper Importer

When you are opening a PDF paper by the PDF viewer, you can import the paper to Mendeley Library directly. Notes: ・If you use this extension, you have to register your Mendeley's account. ・It only works when you open a PDF file by PDF.js viewer or chrome's default pdf viewer. Other viewers are not confirmed.
