So what so you think? There are so many of them, and so many are incredibly good... Maybe we can have a compilation of the best ones we have use. I like a lot jQueryCorner, which is really helpful for making the round corners, but you can use it in a lot of ways. jCarousel of course, and jqueryfancyzoom is another one that I like a lot. But, I will put more later. I kind of new with jQuery since I was a prototype/scriptaculous user, but I'm really astonished with jQuery and the immense community that seems to use it and develop plugins for it.
