Oh and another feature that I'd like to try is to auto generate character pics for each person in a story, so that if you come back to it you can check their pictures. That would be very helpful for me. It could generate until you find one you like for each person and then auto load the same image when you highlight their name.
I had a play with a text generation tool textcortex.com :
"give me a 1 paragraph description of the physical features of the top 10 characters in the book Guards Guards by Terry Pratchett. These should be about 3 sentences long. make each description longer. even longer." (they were a bit short so I was just adding to it. A better prompt style could likely be used)
which gave:
Lord Vetinari: Tall, thin, and immaculately dressed with a calm, calculating gaze that belies his sharp intellect. He has a long, hawk-like nose and a receding hairline that adds to his air of authority. His finely tailored black suit with a high collar and a long, sweeping cloak gives him a commanding presence.

I think that might be on to something, and it gives 10 free requests per day, so that should be enough to grab the descriptions for a book
