The new options for layer / container placement are a godsend! But I was playing around with it just now and I think there's something wrong with the breathing effect:

When I turn it on, the picture completely disappears. I tried messing around with the "Power" value and when I crank it up really high -- say, to around 0.05 -- I can see the top of my picture (in my current instance, it's the very top / head of a character bust) flickering at the bottom border of the screen. I have no idea what in the world is going on there, but I have a Visustella plugin that has the exact same feature and it works fine, so I guess that's a work-around for me, if I actually need that feature... Although it can only apply that effect to it's own generate pictures, and not the ones generated by your plugin.
