This utility plugin changes the theme of the current user to Sunrise, and uses the Sunrise color scheme when browsing the front-end, to help ensure you are viewing and editing the Development Site when making crucial changes to a site.
This plugin also adds a menu item to the admin bar to further confirm that you are on the Development Site.

You just have to activate the plugin and go building your posts, pages or projects; you will find in the Divi Audio module some new design options both under the ‘Content’ tab (‘Audio Timeline Margin’ setting under ‘Audio’ toggle and ‘Image Width’ under ‘Image’ toggle) and in the ‘Design’ one (here you will find at the top a new ‘Audio’ toggle to customize timeline colors and other).
