Hi Varian..I was playing with it for awhile and found quite a bit of guess work is involve. Not sure how well you can have control over the effect you want with the "stack" option, but I find that what I see in the preview window is not what I get when applied sometime. Works only for the first application to an image. It get worst when you do a second effect over the first. Most unpredicatable result when you zoom in more then 60% in preview. I have two occassion when I see something I like but when applied, got a blank screen. I'm referring to version Pro 1.03 However, stilla very useful plugin to a certain extend. IMHO..I still find WYWYCG (What You Want Can Get) with control with a good paint program for this kind of stuff...guess there is more work.
