TinyMCE Plugin: Feature Box

This adds a “feature box” button to the TinyMCE content editor. Click the button and the HTML markup for a feature box appears in the editor. Use your theme’s editor-style.css to style it in TinyMCE to match the frontend.

This saves users from clicking “HTML”, typing <div class="feature-box"><p>Feature box content goes here</p></div> , then switching back to Visual to edit it.
