I've been able to do a certain amount of styling via CSS, but I'd like to add divs and more to the navigation elements - in other ords, I need to be able to somehow edit the actual js file, but obviously don't want to do so since it would just be overwritten on future updates. Surely there are functions/hooks that would make this possible? Or, would it work similar to how other theme files operate in that simply creating an identical file structure (includes/js/thickbox/thickbox.js) within my theme it would automatically overwrite it?
Help! The out-of-the-box layout is way too generic for my tastes.
