Nodes increment by 0.1, can this be changed? I was looking at the sliders on nodes and I wanted a more dynamic change. When, for example, on the Fresnel node, slide it up and down it will increment or decrement by 0.1.

Is there a way to modify this behavior so that it will change by a value of 0.001 for instance?

This may be hard coded. I'd like to know how to modify this for a smoother experience transitioning between values.
Trying holding down the shift key while clicking and dragging to change the values. This will allow you to increment the value by hundredths versus tenths.
