A feature that would allow you to zoom in with the camera block using inputs. An example for an input could be "Activate1" or "Vtol" In xml you would be able to set the standard zoom "1" being 1x zoom/standard and 2 being 2x zoom. So if a camera had the max zoom of 2 you could use an input like Vtol to zoom in gradually up to 2x. An input like Activate1 would ofcourse just zoom it in automatially.

In summary, let cameras have a zoom in feature that has a max zoom in and the zoom would be controlled using an input.
