It would be nice if AD could create interactive prototypes for wire frameing. This could be handled by attaching actions to objects and then turning on / off certain layers. You could also allow the action to go to a different page or artboard (I know artboards are still coming). You could export the whole thing as an interactive SVG for viewing in a browser, or export as html. As many designers use multiple tools to handle this already, you would be doing everyone a service by combining all the tools in one. Just my opinion.
