Ever using none plotting layer in acad, they are sorely missed, when everyone discocvers the usefulness of them for putting reminder notes and team notes so they are not missed but seen. Better yet I could also see something like this as not even being visble in the plotting sheet layout. Don't care right now if it were one, but would be nice to have atleast 3 of such layers. A special line or color would be order for such a layer.
