Thank you very much! I'm eager to test the coming new version!
Just one question. How did you implement your Darken mode?
Is it: (1-r) B + r Darken(B , A)
Or is it: Darken(B , (1-r) I + r A)
Unlike what's goes on with Multiply, those two formulas are not equivalent! I'm not sure which one is actually the best. Whereas I think the first one is more logic, the second one could be more useful.
