Intro: In the root page of the book, there's an index on the bottom that lists all the child pages. There are also links to previous and next page in each of those child pages. Not sure what the correct terminology is for that index.
My problem: What I would like to do is to completely re-design those links. Since the book contains mostly videos, I want each link to have a thumbnail of those videos. Of course, I would modify the content type of the page to upload that thumbnail image. If I could replace those pages with a panel and a view block for example, that would completely solve the problem. (but not sure if it's possible to create such view to list the child nodes)
Question: Is there a module to redesign those indexes and/or what are the templates I would need to modify to do that? Thanks!
