A simple interface to edit or delete Custom Fields.
This plugin offers a simple interface to edit or delete any Custom Field names/keys you may have created in the post/page editor.
Deleting a Custom Field also deletes the associated content, so use with caution!
This is not meant to be a powerful plugin in the vein of Advanced Custom Fields.
I have only tested this in WordPress 3.5.1, but it may work with older/new releases.
Only users with role Editor and above have access to this plugin.
