Useful and recommended

For development, this has come in quite handy for quickly finding meta keys and values on a particular post type. It is simple and straightforward.

I can think of only two things that would make this more useful for me personally:

1. The ability to restrict viewing and/or editing to particular user capabilities and/or user roles
2. A place to see all available meta keys, in order to quickly switch between different post types

That said, this plugin is way more convenient than digging through database entries. Many thanks for creating and maintaining this.
