The "Use sound?" option isn't saved, so if one doesn't want sound, (s)he has to turn it off each time. Not everyone does, and so it scares some users something fierce when suddenly something is blaring out of their speakers (see the archive for today's instance, which prompted my suggestion).
Regarding jQuery, JavaScript libraries suck because they have to be loaded and parsed entirely every time, even if only some of their functions are used. This slows down loading and operation unnecessarily. In most cases jQuery isn't even needed today and has been resorted to out of laziness.
Don't worry, I'll experiment with my own board style, as usual.
