The Easy Genesis plugin allows you to make many customizations and setting changes to your Genesis-powered site, without having to write custom code. You must be using version 2.2 or higher of the Genesis theme framework and the Easy Genesis plugin.
This extension allows you to universally remove titles across your pages, and display the featured image (if there is one) at the top of your pages. You may need to write custom CSS to style the featured image the way you want.
Note: this plugin is no longer necessary, as it has been rolled into the main Easy Genesis plugin.
