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.
Please [let me know](http://uwmike.com/contact/) if you like this, or encounter any issues/bugs. If you’re feeling magnanimous, I [enjoy presents](http://www.amazon.com/gp/registry/wishlist/TQSNUS2H0Z42).
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 2.5.1 or 2.6 required)

As far as I’m aware, this functions as designed on 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.
