Extender Pro is all about site-specific customization. And what I mean by that is that it allows you to create completely theme-agnostic custom styles, functions, scripts, templates, Widget Areas and all kinds of content, code and control. It effectively EXTENDS the active WP Framework by providing a completely compartmentalized development environment. There’s little you can’t do with the Extender Pro Plugin. It’s definitely one of my go-to WP DEV tools!
