If I choose Import References and choose multiple files (all using the same RIS formatting) it only imports one of them.
This is sometimes annoying if I've spent a lot of time digging up sources from the web and in the end I have a bunch of pdf's and several dozen separate reference files.
---EDIT----
Disregard this! Sorry.
I just realised that if I drag and drop all the files onto Bookends, it processes them all one by one.


(But how about making the Import References feature to accept multiple files to make that more useful?)
