<p>Slim Mobile Theme Switcher is a developer-friendly, lightweight solution for sites that need a dedicated mobile experience without the overhead of a heavy mobile plugin. This plugin targets mobile handhelds, ensuring tablet users may still enjoy your full desktop-grade layout.</p>
<h3>Key Features</h3>
<ul>
<li><strong>True Mobile Detection:</strong> Uses refined regex to separate small-screen phones from tablets (iPads/Android tablets).</li>
<li><strong>Manual Overrides:</strong> Allow users or testers to force a view using <code>?theme=handheld</code> or <code>?theme=active</code>.</li>
<li><strong>Persistent Choice:</strong> Option to remember a user’s manual theme choice for 30 days via cookies.</li>
<li><strong>No Bloat:</strong> Zero front-end CSS or JS added by the plugin itself.</li>
<li><strong>Developer Friendly:</strong> Built by a developer for developers.</li>
</ul>
<h3>How It Works</h3>
<p>The plugin uses a precise, two-step detection process to ensure the best user experience:<br />
1. <strong>Exclude Tablets:</strong> High-resolution devices (iPads, Android tablets, Kindle Fire) are served the Desktop Theme to take advantage of their screen size.<br />
2. <strong>Detect Phones:</strong> Handheld mobile devices (iPhone, Android Mobile) are served the Mobile Theme.<br />
3. <strong>Manual Choice:</strong> If a user manually switches via URL, their choice is honored for 30 days via cookies.</p>
