I see the following future features:
* Support taking video: Technically possible but this is some long term stuff
  if nobody steps in and adds code for it or gives me some woirking gstreamer
  code for simple switching between image and video mode.
* Delayed photo taking (timer): This is a simple application extension and I
  might add it in the next weeks.
* Changing image size: I need some gstreamer know how for this to query
  supported image sizes and to be able to switch between them on the fly.
* Taking photo series (take X pictures as fast as possible). This would also
  be a simple thing to add but I do not have any personal need for this.
