Most commonly taxonomy sorting plugins will create a new interface to drag or order/sort your terms. This plugin uses the built-in view just to make things easier. Just grab the term and drag it to a new position. No more extra clicks – everything is saved after repositioning!
The order is applied to term queries that did not ask for an order of their own. A query that explicitly sorts by count, slug, term order or anything else gets what it asked for, so themes and plugins that sort terms themselves are left alone.
