Have you been curious about the WordPress Theme Customizer?
It’s used by many theme designers to allow users to quickly preview and customize themes from the admin interface, but many VIPs are using it as a way to give editors and content owners more control of the site’s appearance without having to delve into the code. The Theme Customizer can allow them to preview and publish significant personalizations or changes to a site’s home page (or other page) with just a few clicks, allowing for the editorial team to react quickly to the latest news stories.
