Changing node connections to be straight? As is typical in this kind of thing I have a node tree filled with tangled curvy node connections going every which way. Even using reroutes it is somewhat difficult to read.

I've seen a number of people who have the node connections appear far more like a straight line than a bezier curve...how would I replicate this feature?
