Zoom Continuous Sensitivity

I've been using 'zoom continuous' when using a tablet/stylus. I've found it better than the normal method since you don't need very big movements to zoom close in or way out. It's quick and responsive in the 3d viewport and UV editor, but in the animation (Graph, Dope) & Node Editors its quite slow.

I'd like to suggest a 'zoom continuous sensitivity' property, similar to the 'orbit sensitivity' property, to make the continuous zoom more responsive in the different animation and node editors. So probably a separate adjustment for 3d/UV and other views.
