Extended Options keeps meta data and certain WordPress tweaks persistent regardless of the active theme without editing any theme files.

Extended Options manages certain meta data and content add-ins from within the WordPress dashboard. This plugin adds the capacity for meta data and content added to the footer and <code>head</code> areas to be kept consistent regardless of a theme change or upgrade.
Extended Options is for WordPress 2.6.x and, more specifically, manages following meta links and tweaks:
<ul>
<li>Archive meta links</li>
<li>Relationship meta links</li>
<li>Favicon meta links (blog and dashboard)</li>
<li>OpenID meta links</li>
<li>MicroID meta links</li>
<li>Geo tag meta links</li>
<li>Robots meta links</li>
<li>Enabling/disabling author archives</li>
<li>Enabling/disabling 404 headers</li>
<li>Enforcing <code>www.</code> preference</li>
<li>Protocol discovery meta links (Atom, RSD, WLW)</li>
<li>Enabling/disabled generator meta link</li>
<li>General meta add-in content</li>
<li>General comment form add-in content</li>
<li>General footer add-in content</li>
</ul>
While this collection of meta data and tweaks appear random, these are specific modifications I grew tired of making whenever I activated a different theme or upgraded an old one. I needed a plugin to manage these needs that didn’t overlap significantly with other plugins I used.
Special thanks to some awesome code integrated (and possibly modified) with Extended Options.
