I believe MEP generates little triangles for all devices with wire connectors not actually connected to wires. We do not connect the wires, but we do assign devices to circuits with circuit manager and the electrical properties (which is painful and inefficient, but that is another topic).

I would like to the ability to generate the warnings for devices not assigned to a circuit, and to turn off the warnings related to no wire. Then I could step through each device and fix the missing circuit assignment.
