Extra Options plugin for WordPress is a small collection of tweaks to improve WordPress publishing experience and site performance.
Extra Options strives to be light, simple and discreet. Everything in it is optional, it does nothing by default, it does not touch your content, and it cleans after itself.
Extra Options offers options for the following:
Content filters control
Document HEAD control
SEO (everything you need and nothing you don’t)
Loading AJAX libraries from Google
As weel as a couple of miscellaneous tweaks
