Seth Smigelski

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.
<h3>Key Features</h3>
<ul>
<li>True Mobile Detection: Uses refined regex to separate small-screen phones from tablets (iPads/Android tablets).</li>
<li>Manual Overrides: Allow users or testers to force a view using <code>?theme=handheld</code> or <code>?theme=active</code>.</li>
<li>Persistent Choice: Option to remember a user’s manual theme choice for 30 days via cookies.</li>
<li>No Bloat: Zero front-end CSS or JS added by the plugin itself.</li>
<li>Developer Friendly: Built by a developer for developers.</li>
</ul>
<h3>How It Works</h3>
The plugin uses a precise, two-step detection process to ensure the best user experience: 
1. Exclude Tablets: High-resolution devices (iPads, Android tablets, Kindle Fire) are served the Desktop Theme to take advantage of their screen size. 
2. Detect Phones: Handheld mobile devices (iPhone, Android Mobile) are served the Mobile Theme. 
3. Manual Choice: If a user manually switches via URL, their choice is honored for 30 days via cookies.
