How about subcategories?

Hi. I installed this, it looks great. However, I would like to sort not only the order of categories, but also move some categories from top-level (no parent) into other categories. And reversed: move subcategories out of their parent.

Can this be done somehow? I can’t seem to be able to do it anyway.
