overall opacity slider

[Tomala]

i have question to Rory, will you consider something like this to implement to midi2lr?:

so on with turning midi knob will proportionally add values to overall effects or decrease it? 

i' am asking coz your software already knows all off the slider values for a picture, and maybe you can write smart algorithm for that, just tell me if it is possible and will you think about it?

can't wait what you think about it.

Are you talking about “fading” presets or adjusting multiple parameters proportionally together?
