My Page Order allows you to set the order of pages through a drag and drop interface.
My Page Order allows you to set the order of pages through a drag and drop interface. The default method of setting the order page by page is extremely clumsy, especially with a large number of pages. The plugin also installs a replacement widget that exposes all the options of the wp_list_pages template function.
My Page Order has been out since WP 1.5 (2006) and hasn't really changed since then. As of version 2.8.6 of the plugin I'm breaking backwards compatibility to add new features like a replacement widget. Keep using version 2.8.3 if you are not on WP 2.8 yet.
