It would be brilliant to have integration with my Google Scholar alerts. I have no idea how or if it could be implemented, but it would be a dream to have a Paperpile folder that was automatically populated with the citations that I get e-mailed from Google Scholar Alerts.
This is actually planned! It will be part of a side project the team has been working on, which should see the light of day once we’ve implemented some major updates of the web app over the coming months. Either way, I’m adding your +1 to the topic on our internal tracker.
