Does anyone know if the pinch zoom work around will be available as an addon or something in the future? Extra?

This would be slightly handy for us to use the web browser and to zoom an image or something. I like the idea of drawing a straight line and measure the distance to zoom the screen.

This idea is great. Could any developer make this happen?
