This plugin allows you to change the order in which plugins will be loaded by WordPress.
It shows you a simple drag-and-drop interface to set this order.
If you are plugin developer, I encourage you to use actions and hooks so that you will not need this plugin at all, but if you are managing your own blog and you face to the problem a plugin depends on other one, then this is the plugin you need.
This plugin is available for download to be used on your WordPress self-hosted installation.
