IKList specializes the list class in two ways. First, it incorporates reference counting to take care of automatic memory management. Second, it conforms to the IKIconObject protocol so that it can display itself and be dragged around the workspace.
A typical use is to represent a multiple selection in an IKBrowser. The icon of an IKList is the hand-and-sheaf when there is more than one element in the list; otherwise it is the icon of the first element.
