I agree with the sink/source idea, but I actually think the wire is a great way to represent that. Maybe all you're asking for here is the ability to adjust the brightness of the error (or other) wires? Then you could make them really light (but not transparent) so they are less confrontal. I dunno - every since NI made error wires their own special baby-poo-brown colour, I've been able to tune them out unless I'm specifically looking for them. I also usually line everything up on the error wires which makes that tuning out even easier.
Back to layers: maybe we could combine layers and brightness? If we could define layers and have all wires that aren't in currently selected layers to be very light gray? Should we be limiting the dicsussion to wires? In CAD, layers are synonomous with common functionality, so it might be a good idea to group primatives, subVIs, wires, control nodes, etc into layers. Then when you mouse-over something maybe it could highlight everything on that layer?
