I like the idea of a special layer (doesn't have to be called demo). If on that layer DM doesn't show it in any schedule as a count. Those devices would also be ignored during a find uncircuited command.

Sandy--Inserting devices on a demo layer is currently possible. You need to create a new layer system using the DM Electrical->Customization->Layers command. Once the new layer system is created, when you insert or query a device you can choose the new system.

I would just like to be able to place devices on a demo layer.
