This plugin allows you to order:

• Pages,
• Categories, and
• Posts

using a simple drag and drop interface:

The good news is that the latest version of WordPress now provides a term-order field in the term relationships table - and so it is no longer necessary to upload a tweaked taxonomy.php file - as we had had to in the previous verison. While this was done automatically by RapidFormatter, it’s always best if you don’t have to start modifying some of the base WordPress files.

So the end result is a custom-ordered Categories listing, instead of the default alphabetic listing :

A quick test of the Manage Page Order also resulted in a re-ordered listing of pages (much easier using drag and drop than messing around with setting values in the page order field).

So - it appears that this RNW plugin can be used as is with WordPress 2.5, and with the bonus that it’s no longer necessary to tweak the taxonomy.php file.
