I love Paperpile - I have used many of the other citation management tools and Paperpile works better and is simpler to use. Brilliant.
One thing that I would love is to have an option in the workflow for a csv file instead of a bibtex one. If Paperpile could constantly update a csv file in Google Drive then this csv file could then be synced or copied to many other programs like Airtable, Mindmap programs like MindManager etc.
Great work and keep it up!
