Rotating Featured Products / Where is Listmania? Hot Deals?

We want to select a dozen featured products but only show 3 at a time in the sidebar. It can either randomnly choose 3 of the 12 or rotate through them. Anyone done this or know how?

Also I see references to listmania in setting up featured products yet I don’t see any listmania in Admin (ver 2.0.14) Was it taken out or am I not looking in the right place?

What is the difference between Hot Deals and just a regular Manual Product block aside from the fact Hot Deals only works in the center section?
