Virgin Kalactic v1.5 --- NodeToggle
NodeToggle is a PartModule, automatically added to all parts by ModuleManger at startup, which allows you to disable AttachNodes on any given part individually via right clicking on that part in the editor. This will aid in situations where nodes are congested, making it easier to attach the part where you want it without it snapping to a different node. It may also help to reduce unnecessary drag in FAR, this hasn't been tested much yet.
