I'd also like a way to see the list of quests that are active and those that are complete. To keep with the book theme they have going on (and maybe I missed it), there could be a Table of Contents page.

There is already. Click on the NEXT PAGE icon, lower right corner, of each page. Each Quest has its own page in the Book.

Not quite. Cycling through pages is not the same than having a page with all quests titles

Exactly

I'm not sure how King's Bounty handled it, but I've grown enamored of the idea of a book where the table of contents is the list of quests and clicking on the ToC entry takes you to the details of the quest.

Still, anything beyond clicking Next through page after page of entries would be a welcome improvement.
