<p>This is a fix of Top Level Category plugin for WordPress 3.1. and further versions. It’s purpose is to provide the same behavior as the original plugin, but in new WordPress versions.</p>
<p>The Top Level Categories plugin allows you to remove the prefix before the URL to your category page. For example, instead of http://foliovision.com/category/work, you can use http://foliovision.com/work for the address of “work” category. WordPress doesn’t allow you to have a blank prefix for categories (they insert <code>category/</code> before the name), this plugin works around that restriction.</p>
<p>This plugin works also if you have a permalink structure like %postname% or %category%/%postname% — this wasn’t possible in the original version. However, this feature might not work properly for child categories at this point. Test carefully!</p>

This is a fix of Top Level Categories plugin for Wordpress 3.1. and above.

<p>When you change the permalink structure then this is a problem for bookmarks of users and also for search engines to link to your posts. This plugin uses the slug of the new url and search for a ID in the database of WordPress. If it finds a post according to the slug, the Plugin will redirect to the correct post and send a header message “moved permanently 301” to change the url on the index of search engines.</p>


Change Permalink Helper

Awesome!

It checks the Permalink and redirects to the new URL, if it doesn't exist. It sends the header message "moved permanently 301"
