@batpad hey... yaay! so,

1. As a user, I'd like to be able to create a custom close button, that I can style independently with CSS. I tried to do this on a jQuery object and trigger the close button click, but it didn't work.
2. Look at the navmarkup option. That may need some looking into, in a bit :p
