AIM Style Vault lets you add persistent CSS to your WordPress theme that can be organized into stylesheets and published 
just like a post. You’ll never again have to worry about losing changes made to the style.css file of your theme. In fact, you 
can switch back and forth between themes and use AIM Style Vault stylesheets to preserve special styles for each. The AIM Style 
Vault stylesheets are generated using a custom post type, then compressed and served to the document header, 
resulting in the fast application of custom CSS. Stylesheets are applied using the top-to-bottom cascade so that recent stylesheet 
entries will override earlier entries.
Requirements: 
AIM Style Vault requires that the wp_head() tag is included in the theme header.php file. If it is not present, contact your theme’s 
author and request that it be included.

<ul>
<li>Unlimited Custom CSS Stylesheets </li>

<h4>Simplify Your Editing Life</h4>
Requires your various post types — as specified in a simple options page — to have a featured image set before they can be published. If a lack of featured images causes your layout to break, or just look less-than-optimal, this is the plugin for you.
Rather than forcing you to manually enforce your editorial standards of including a featured image in every post, if your contributors fail to add a featured image to a post before publishing it they’ll simply find it impossible to publish.
<h4>Setting up the Plugin</h4>
By default it works on the “Post” content type only, but you can specify other content types, or turn it off for Posts in the new options page in your left sidebar: Settings > Req Featured Image. Simply check and uncheck the appropriate types, set a minimum image size if you desire, hit save and you’re all set. Happy publishing!

Does what it needs to do

Requires content you specify to have a featured image set before they can be published.
