Excellent tutorial, however

The tutorial is excellent, however, there is no way to make the image larger than 7" x 12".
No enlargement box, no handles to enlarge. It looks like a post card on my 27" MAC.
If I had known the video was the size of my iPod I would not have purchased it for my computer. Please remedy this because the tutorial is excellent otherwise. The app itself should get 10 stars, but the size of the video brings it down.
