Setting the category and listing order


has anyone worked out if there is a way to set the order that categories are displayed, at the moment it appears to be alphabetical order.

I am trying to convert a large site from a perl directory set up to work in this Directory plugin, the old site is here:

as you will see the categories are in a specific order, these are manually set by popularity and this is what would like to be able to achieve in Directory.

Same with listings within categories, these appear to be shown by newest at the top which is fine but on the old site I offer a paid sponsored listing which is a person buys it movers their listing to the top of the category their link is in, again can I do this with the listings?

I understand there is a new version being released very soon so maybe some of these question will be answered there.

Thanks in advance
