Hello, it would be extremely nice if we could get the ability to download a paper on import. So the workflow would look like this: Search for a paper online. Click import, the citation is added to your bibtex file. The Document gets downloaded and stored in a unified way in a predefined folder so that in the end, you always have a copy of all the references you are using. Please make this happen! Cheers!
It is already possible to associate local files to entries by copying/moving next to the BibTeX file as well as renaming a PDF file to match the BibTeX key. As you request, a logical extension would be to (automatically) download the PDF file if URLs or other references are provided in the BibTeX entry. Implementation is postponed until I have time to write some code ...
