Many thanks to all those who have already posted here. I’ve managed to get ORB and org-noter (mostly) working in my spacemacs setup.
Any suggestions on best practice for articles, such as web page snapshots, that don’t easily fit into a BibTeX world? E.g. at the moment I dump web pages I want to be able to remember and search into a PDF, and index them in DevonThink. I’m guessing some kind of org-noter link in an org-roam note is likely the best option?
