You’ll have to turn your home.php file into a page template by adding this at the very top (under the first php)
// Template Name: Home
Then whenever you create your page, select the Home template (or whatever you name it). Keep in mind, it will still show the widget content on this page, just as it was on the regular home page.
You’ll be able to use this template as a “page” but if you’re trying to add content from the content editor I’m not sure if it will work out of the box or not without adding customizations or the code that is needed to add content – didn’t know if that was what you were trying to do or not…..If so, you’ll have to create some code for the content to show up in the place that you want. It would probably be easier to just add the Genesis Featured Page widget inside of one of the widget areas like the Welcome or Home Bottom Message (since they are wide)….or you could just create a new widget area to display a Featured Page.
