There's a few templates included with the script - but it would be even better with more. If you're a designer and want to contribute something, why not make a template?
Instructions on how to make one are in the downloaded files. There's only a couple of conditions: it must be all your own work; and, wherever possible, it should use the same structure as the included ones (with a <ul> </ul> for the menu and so on).
If you've any questions on designing one, feel free to
get in touch!
