For books, I'd like to see an option on the course card where the table of contents can be displayed or not displayed (at the book level). Having all the contents displayed pushes other course items on the page down requiring scrolling. This is awkward if using multiple books in a module.

OR

If it had a function, similar to pages, a user could click a "view contents" link to expand the topic titles on the course card without going into the book.
