Add Custom Post Type Slugs to Admin Body Class

Details
View on WordPress

When in Admin mode, this plug-in adds classes to the <body> tag to let
your CSS know where you are.

For example, if you are viewing the list of all your Posts, you would get this additional class:
edit-list-post
And, when you are editing a Post, something like this:
edit-page-post

Alternatively, for custom posts, for example “movie”, you would see either:
edit-list-movie
or:
edit-page-movie

This allows you to write custom CSS and JS to interact with these varying edit pages within WP.

Please let me know if you have any questions/suggestions/thoughts,
