Hybrid Hook Widgets is a plugin that creates new widget areas for the <a href="http://themehybrid.com/themes/hybrid" rel="nofollow ugc">Hybrid theme</a> and attaches them to the theme’s action hooks. Basically, it allows you to add widgets pretty much anywhere.
Typically, to add extra stuff to the theme, you must use one of Hybrid’s action hooks. This can be quite confusing to some users. This plugin was created mainly for those users without much XHTML and PHP knowledge. It allows them to take advantage of Hybrid’s advanced hook system without the need to understand how it works. Of course, even advanced users can take advantage of this, especially when dealing with client work.
This plugin is for WordPress 2.8+ only.
You must have the <a href="http://themehybrid.com/themes/hybrid" rel="nofollow ugc">Hybrid theme</a> installed to use it.
Full instructions for use can be found in the plugin’s <code>readme.html</code> file, which is included with the plugin download.

This plugin allows you to do all this from a simple administration menu, and assign widget areas to sidebar locations with simple drop-down menus within the post/page edit screens, or when editing a tag or category.
