Sharing a library/ multiple users accessing one library

Welcome to our forum, @Schneider_Reto. Significant changes for our extension and interface are currently in beta; although this version does not yet include sharing updates these are planned to be implemented by spring.

In the meantime, the best way to achieve this would indeed be using our shared folders for collaborators to access, add & save papers (which will include original documents and annotations made up to the point of sharing).
