Hi there, The last year I had to make a lot of animation with jquery and I ended up including custom plugins and extensions for adding support to animate from one class to another and to have a delay. All the plugins in the jquery plugin repository to do this are not documented quite well and the result when using these to enhancements together is quite messy. So I'd like to propose to include these to enhancements into the core. animate( .classname | style rules , [duration], [easing], [callback], [delay] ) Regarding the delay: I could imagine an event extended timer function to be integrated not only for effects like here: http://plugins.jquery.com/project/timed-event other links, mentioned above_ delayed animate execution: http://plugins.jquery.com/project/dAnimate animate to class: http://plugins.jquery.com/project/animate-to-class http://plugins.jquery.com/project/classAnim
