Display order is not substitute for automatic sorting as you have to manually set order for every (sub)category. If you have 100+ subcategories this is a major pain in the a**.
I cannot instal version 1.1.2 -->
SimpleXMLElement::__construct() [simplexmlelement.--construct]: /tmp/phpcGjcyT:1: parser warning : Unsupported version '1.1'
Is it possible to extend this functionality to also sort subcategories? I have three categories and 100+ subcategories which cannot be quickly sorted right now.
