The rotate method is being removed from the jQuery UI Tabs widget.
I make use of this method, and have extended it to allow pausing/unpausing.
Since they are removing the method, I have created an extension that contains it as well as the pausing/unpausing functionality.
Actual documentation coming by early June 2011 (sorry!). Until then, you can see it in use at finishline.com
Working on a reference implementation here, but it isn't finished (or even working) yet.
