The actual metadata extraction is very poor. Could you implement a communication with Zotero in order to use the metadata retrieved from it? Or implement the Zotero’s functionality directly in Remnote?
Not a solution, but, I’ve a CSL that “speaks remnote”, allowing extractions of Authors, Journals, Issues Year, systematically.
