> How is this done in Orcad? In Eagle? In other tools? Since it's an internals problem, and not a user interface problem, we have no way of knowing.
PCB at the moment has a fundamental limit of 8 layers, and assumes all eight layers are copper. The rest of the layers are deduced from those. Changing its internals to have a virtually unlimited number of layers, and explicit layers for such annotations, is a technical problem, not an interface problem.
