P: Using scroll instead of vertical point movement

In Development module, color mixer or sharpening the idea is to press and hold with mouse, and move the slider left and right. This is not a very accurate way of changing the settings and I believe using the scroll (mouse or mousepad) would enhance this part of the edit process. 

For example: One could select the exposure setting, go in to ‘move slider by scrolling’ feature and scroll comfortably up and down, until a preferred lighting has been achieved. 

Can you understand my explanation, and what do you think?
