This makes it so much easier to navigate the docs. Great work!

Two general feedback points that can be fixed here or as continuous improvements somewhere else:

1. It would be more readable and easier to maintain if we just had a good word separated and capitalized page name and not have the top level header repeating the same info or even saying something else. The exception is generated pages where the header have a programmatic meaning.
2. It would be a bit easier to navigate if link names and page names matched everywhere.
