I would like the ability to save EACH iteration. So if I have 50 steps, it will generate 50 images show me what it looked like at each step. I've found that sometimes I have a good start to an image at 50, so I bump it up to 200, but then I find that 100 actually turned out better than 200 because 200 wiped out some features that I liked, etc.. just a thought :)
