I love using GoodNotes with the outline feature for digital journaling. The only thing missing is that physical A5 book to hold in your hands. It would be so amazing to have a service to order a bound book once 250-300 pages in an A5 style notebook has been filled. Also to have a journal notebook option where page numbers are added, A5 is default, and landscape mode allows for a full 2 page spread to be shown. We get an amazing feature and it's monetizing for the devs. Win win.
