There's no parameter for this. I'll add it in the next version.
I'll have a look at this too, it shouldn't be too hard. Is there a morph in particular that's bothering you?
For me - and this is a problem with VAM overall - but when ladies SMILE it is often like a psychotic joker smile. with your app it is nicer than most but it would be still nice to lower the multiplier on smile especially. like morph extremity I suppose. thanks\, just an idea!
