This plugin hasn’t been tested with the latest 3 major releases of WordPress. It may no longer be maintained or supported and may have compatibility issues when used with more recent versions of WordPress.



Our work for themes.php was included as part of core WordPress in version 3.8. This plugin moves on to focus on the installation screen now.

This plugin is an ongoing experiment around improving the theme experience in WordPress. This is meant only for development work, and the brave of heart, as it totally breaks themes.php.

Discussions will happen at the WordPress make p2s. Check if you’d like to participate. All comments and contributions are welcome.

(Plugin assumes the mp6 UI.)
