Hybrid Hook Widgets is a plugin that creates new widget areas for the Hybrid theme 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.
