Re-order categories by switching theirs ID's.
This plugin allows you to re-order categories by switching/swapping theirs ID's. Once it's done, the plugin can be uninstalled: it is clean and straighforward.
If you do it on a long-time running blog and running many plugins, please do a backup of your database. This plugin updates the WPML databases as well, but it might cause troubles for other plugins (please let me know if it is the case and I will support them).
Thanks to Roman for his ideas from which this plugin is inspired from :)
