Thanks for your comments on how labels operate in shared folders, @SergeiWallace.
Currently, in shared folders, you can:
- Assign labels to references shared by you by dragging the reference into the label in the label tree.
- Assign labels to references shared by others by dragging the reference into the label in the label tree. Then the “Add Paper to Library” dialog opens where Paperpile lets you know that 1 shared paper is about to be added to your personal library and labeled with the desired label.
But the sharing features have been rewritten by the team and there will be changes to shared folders that will be part of the new Paperpile in beta, which should take care of issues like this.
