Great stuff Tim! Definitely work it in and contribute it. We need more of that versus less, and who better! Certainly if it can be enabled and disabled with a check box in settings it would be great; then can AB test for which should be the default later. Maybe we should start some Apache NetBeans feature surveys :-)
