Dr Ohh, do you not understand what I'm seeking? Although wordy, I think I've set it out.
Having now deleted all the tags in my library and wanting to use the installed plug in to refill the tabs from Goodreads, what are the mechanics pls to solely group process only the tabs? i.e. I don't want to have overridden any of the other fields, such as author name when using "Edit metadata in bulk", and haven't yet found a way.
