When in Admin mode, this plug-in adds classes to the <code><body></code> 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,
