<p><strong>Sticky Postbox</strong> is a piece of code written few years ago as exercise to learn how WordPress handles administration meta boxes’s availables statuses (closed, hidden and sortings).</p>
<p>This very lightweight plugin adds the <em>sticky</em> feature to administration meta boxes allowing them to be sticky at top right corner of the browser window.</p>
<p>Only one meta box can be sticky at once, so a new sticky meta box unstick the current one (if there is one).</p>
<h3>Basic Features</h3>
<ul>
<li>Per-user settings.</li>
<li>Multisite support.</li>
</ul>
<h3>Usage</h3>
<p>Once the plugin is installed and activated you can sticky administration meta boxes using sticky icon (it appears on the top right corner of each box).</p>
<h3>API</h3>
<h4>Constants</h4>
<p>You can use define following constants in your <em>wp-config.php</em> file.</p>

<p><strong><code>STICKY_POSTBOX_GLOBAL_OPTIONS</code></strong></p>
<p>In a Multisite installation, allows to shares user’s sticky meta boxes settings across all his sites. For example, if you sticky <em>Publish</em> box in editing Pages in a specific site, it will be sticky on all Pages of all sites.<br />
