Why must I export one at a time? Why can't I just export the entire library to a .bib file?
You can export multiple items by highlighting them and exporting. We are working on better export options for everyone!
No, you cannot. Because Papers does not load the entire library. It lonely loads a subset for display. Currently if I "select all" it only exports entries from "A" to "C".
Same here. I need to export my library together with the attached pdf's
If you load more of your library by scrolling down and clicking select all this will work. We should have some better export options at the start of next year.
