TL;DR

AI summary of the plugin's readme

This plugin is for WordPress site administrators and developers who need to inspect custom field data on posts, pages, and custom post types. It solves the problem of debugging post metadata by displaying meta keys and unserialized values directly in a metabox on the post editing screen.
