Also the possibility for the tabs themselves to be images or image Div.

Or for truly customizable tabs you could do a Div display class with a button ID list, and a Button class that takes the display Div ID's this would then allow for multiple Tabbed layouts from one extension.

Top Tabs, Side Tabs, Tab selectors in the section headers and even an infobox with the tab buttons to change the rest of the displayed page (Transclusion on selection, or similar.)
