JSM’s Show Post Metadata

The JSM's Show Post Metadata plugin displays post (ie. posts, pages, and custom post types) meta keys (aka custom field names) and their unserialized values in a metabox at the bottom of post editing pages.

The current user must have the WordPress manage_options capability (allows access to administration options) to view the Post Metadata metabox, and the manage_options capability to delete individual meta keys.

The default manage_options capability can be modified using the 'jsmspm_show_metabox_capability' and 'jsmspm_delete_meta_capability' filters (see filters.txt in the plugin folder).

There are no plugin settings - simply install and activate the plugin.
