Editing Page Titles1 user found helpful
In order to change the displayed page title go to 'Properties' in the dashboard of your page in edit mode. There you can change the name of the current page.
I have an add-on in awaiting approval at the moment that simplifies managing the page heading, title, page description and metadata description. Keep an eye out for 'Magic Heading' later in the week.
If you get the location of a page wrong, you can drag/drop to where you want it in the dashboard sitemap (but not in the popup sitemap).
