MW Taxonomy

Easy to use wordpress plugin to add a custom taxonomy

Drew Gourley

Order Up!
A series of plugins for WordPress which allow for the ordering of pages, posts, and taxonomies through a simple 
drag-and-drop interface using the available WordPress scripts and styles. The plugins are extremely lightweight, 
without a bunch of unnecessary scripts to load into the admin. They also fall in line gracefully with the look 
and feel of the WordPress interface.

Custom Taxonomy Order

Allows for the ordering of categories and custom taxonomy terms through a simple drag-and-drop interface
