Page Title Override 1.0 Download Module allows a user to manage the Page Title

You can now have the Site Name show up last in the Page Title or hide the Site Name completely from the Page Title.

The module also contains a Content Part allowing a Page Title to be separate from content title.

Note: This module will not work if you have already overridden "Document.cshtml" in your theme.
