It's not in the options, but where do I tweak the php to order the sub-cats by ID or name? Thanks.

And BTW, I just donated. What a great theme this is. Just what I need.

try http://wordpress.org/extend/plugins/my-category-order/ and then set ATO->Category Menu Bar->Sort Category Menu Bar by: to 'order'

Thank you for posting this. I downloaded the plugin but when I got to ATO/categorymenubar I am not able to change the "sorting order of category menu bar" drop down to "order". It doesn't show up as an option. Is there something else I need to do first after installing the plug in?

Sorry. I got it. It's under admin/posts/my category order
