Superfish is awesome.. I sincerely appreciate the fact that the developer considered physically impaired users by allowing the use of keyboard navigation.
There are two things that I think is really needed. 1. better keyboard navigation protocol. In this thread I outline the ideal solution (mimicing mac os x's keyboard menu navigation.) I would appreciate if the developer were to read my post there. 2. Easy support for mega menus.. Check out the front page of http://photobucket.com/ and hover over "what's new" 3. A set of themes that people can choose from. Downloadable and tweakable (okay, this isn't quite as important but would be cool.) I'd really like superfish to become the defacto menu solution and I think these suggestions would really improve it. Keep up the good work!
