<li><strong>Performance Optimized</strong>: Only loads when needed and uses browser idle time when available</li>

<li><strong>Admin Interface</strong>: Clean, modern settings page integrated with WordPress admin</li>
<li><strong>Localization Ready</strong>: Translation-ready with proper text domains</li>

<h3>Preloading Methods</h3>
