I wonder.. if we wanted to have all Nodes support a z property (if not present then 0)..
would that be a VeRy Real possibility to have available?
It might help with.. Alternatives ways of looking at the Flows.
For folks who wear glasses (or visors..)
As a- frame of reference..
if I were just to add a z property to some nodes (in a JSON export) and import them backto the NodeRED editor, it should work.. but would I be creating a hazard that might conflict with existing plans?
