Oh that would be so awesome. Imagine what you could do if all dialogs had the capabilities of map-dialogs. You could make thousands of new missions, where you have to navigate through dialog, and if you reach certain information, or do certain things, it unlocks new things you can say (unlocks buttons) the complexity and quality would increase by a magnitude of orders. And the technology is already programmed (in map-dialogs) They 'just' (?) have to enable it for story-dialogs and npc-dialogs.
