Would be nice the ability to delete tags / quickly untag multiple papers
I was about to open a ticket for the same reason. It is easy to add tags to papers but then once you add a tag to 50 papers, it is really hard to delete them all. You have to do it one by one.
Same to me. I have over 1,000 papers tagged with older categories. It would be at least helpful if the tags can be deleted from multiple papers in a single click.
Just started with Papers, and already need this!!!
