Although in previous versions of Aggregator you could create your own custom templates for jQuery tabs, starting in Aggregator 6 we now have a native jQuery tab template with a custom settings page to choose the tab theme etc.
There are 25 new tab themes included
that work with both jQuery Tabs and jQuery Accordion.
This demo shows one of the settings for jQuery tabs, namely rotation. Tabs can be automatically rotated with a specific time interval and optionally with transitions. In this demo and standard medium fade transition is used.
