LGTM, I'd just suggest indicating that a pages is a "management page" whenever the page name doesn't already contain "Management" or "Settings". I don't know if that'll make a big difference, but at least it might hint that they'll find the page in the management area of the nav rather than in the main, upper part.

I don't feel strongly about including/excluding "management" or "settings" after a page name. I chose to exclude it because I figured it'd reduce confusion about the actual page name to use when looking for it in the nav or using the search bar.
