I would be able to trigger template behavior change based on some variables.
For instance, I would have a text variable with 3 possible values and 3 zones. depending on the value in the text variable, only 1 of the 3 zones would appear.
This is actually is kinda possible. Building right now for a client, though with booleans rather than text, the ability to turn add and remote assignable elements. If I finish a lot of other things I can blog about it.
