Lately the paperpile button is not updating its status after importing paper to a green checkmark but stays as green triangle. As I snowball, it is helpful to be able to confirm the paper in the tab is already in bu just glancing at the button without pushing the button.
Speaking of the notifications on the button, it would be great if it had two statuses: one for when the citation is in in your library but not the pdf, the other if both citation and pdf are in the library.
