This plugin allows you to turn off the default display of the page title as the heading at the top of your pages.
Go to the Genesis > Theme Settings menu. In the Title Toggle panel, you can check the box to turn off the titles on all pages. Alternatively, you can turn off titles for individual pages by editing the page, finding the Title Toggle panel below the editor, and checking the box.
