Is there a way to export a BibTex file for all papers in the library? Next to each folder and tag you can export a bibtex file from the drop down menu. But for "all papers" there is no drop down menu. If you select all papers, you can use the cite button, but this is slow because it generates the text in the modal dialog rather than giving you a link to download the file.
Also, this has been brought up elsewhere, but a BibTex file that lives in Google Drive that automatically stays up to date with your entire library would be awesome.
