Hi kodream!
The knob-response obviously depends on what modules you are using. Shift changes the resolution, but not the curve.
Afaik there is no way of changing knob-behaviour globally (fun idea 
) and the curve of particular knobs should be defined by the developer of the module.
Nevertheless, if you want to change certain knobs for particular tasks, have a look at this thread:
And also: You are in modular - often you can use (processed) CV from other modules (simple case: Offset/Attenuator) instead of a certain knob, that doesn‘t behave like you want it to.
Have fun!
