I was hoping there was some way to filter authors that have notes, from the main search bar, but I remembered this topic where Kovid explained that this isn't possible:

One of the use cases for that search would be to filter titles whose authors have already been processed with the plugin
GR Author Notes.
My current workaround will be tagging the processed titles with "Author Notes OK".
So I come to ask, would it be a convenient addition to have a Mark Books button in the Notes Browser, similar to the one in the FTS window? This way, one could select all processed items in the Notes browser, then hit "Mark Books", then in the main search bar type
not marked:true
to filter GR notes unprocessed titles.
