Customize Posts is a WordPress plugin designed to improve the editing experience for posts and pages through the Customizer. This feature plugin allows users to edit post data and postmeta, providing a live preview of changes before they are saved. It aims to make post editing as seamless as widget and menu management in WordPress, facilitating a more intuitive content creation process.

Key features include the ability to preview changes to featured images and page templates directly in the Customizer, along with selective refresh capabilities for faster updates. Users can shift-click on elements to quickly focus on relevant controls, making the editing process more efficient. The plugin supports editing multiple posts simultaneously, ensuring that no changes go live until the user chooses to save, eliminating unexpected surprises.
