I'd give this 4.5 if I could. It's a fantastic product with more inspiration than I could use in a lifetime, whether you are looking to flesh out something specific, or create and adventure or dungeon procedurally. For that it deserves a 5 star.

My small gripe is the sometimes inconsistent editing of the headings and how they are referenced in the table of contents. The sections that have the same level in a table of contents sometimes don't have the same header text size. And sometimes the section text in the table of contents does not match the header text on the page it references exactly.

Further to that, the bookmarks in the PDF are a huge mess. There are duplicate bookmarks, some out of order, and some nested when others that should the same heading level are not.

Navigating a tome of this size digitally would be far easier with consistent headings stylings, and digital bookmarking.
