Gilles, I tried it, and it's better than the one we had. 
I think the blurring could be stronger, say 20, it still shows relatively hard 
edges. I tried it with 20, think it is good.

The aggressive tool can be taken away, I agree.

But the transparency of the blob is too high, it doesn't really cover the red 
eye (or something is not yet functioning right, the zoomed image does not 
correspond to the flattened image).
