Display Widgets Plugin

Change your sidebar content for different pages, categories, custom taxonomies, and WPML languages.
Avoid creating multiple sidebars and duplicating widgets by adding check boxes to each widget in the admin (as long as it is written in the WordPress version 2.8 format) which will either show or hide the widgets on every site page.
Great for avoiding extra coding and keeping your sidebars clean.
