Linking component is as easy as playing with lego. You drag the thumbnail of the source component, and by moving the mouse over another component, the list of possible parameters will be displayed. Dropping the link on the desired parameter will link the two component together. At the end, when the source component is selected you can see, by reading the label on the link, where this component is used.
Of course all modification done on the interface will, in realtime, update the affected components and their thumbnail. This will provide a view of the action of each component.
