The idea would be to have a type of list of just authors, for example a list of favorite authors. For example imdb has 4 types of lists, titles, people, videos, images. I'm asking to add to what we already have (list of books) another type (list of authors) and, possibly a third type (list of series, where we could put all the series we are reading or have read, etc...)

Would you elaborate on this idea? Pretty sure the team would ask this, too.
From my understanding, you'd like to be able to add an author name to lists whereas now we can only add books. Or is it an option that makes all the books from this specific author added to a list?
