WP-Cats is a WordPress plugin that aids in mass category management.
What does it do?
WP-Cats augments the Manage Posts screen with Ajax controls that allow two-click adding and single-click removing of categories from individual posts.
If a post is filed only as Uncategorized, this category will be removed when any other is added. If you have previously added a category to a post on a page, you can add it to other posts by double-clicking the add-icon.
Save the contents of the source file to wp-cats.php, and upload it to /wp-content/plugins/. In your administration panel, navigate to the plugins page, and activate it. (WordPress 2.3 required)

As far as I’m aware, this functions as designed on IE, Firefox, and Safari. For other browsers, YMMV.
Warning: The code that this interacts with is fragile, and seems to undergo a lot of frequent changes from the WP core team; every point release since 2.0 has broken functionality. If you’re on the most recent WP or a release candidate and WP-Cats doesn’t seem to be working, please drop me a line and I’ll try to help you out. No promises, though.
