This feature is planned as well – it requires a bit of work on both the camera interface, our app interface and our server interface. But it is in the pipeline for more control.
We are considering this feature – the real challenge is that some of our users love the pan/tilt on the camera via gestures – so this makes it more difficult. But we will seriously consider this.
Interesting idea, we will look into it. Probably will be a longer term idea
