Your commit about zone duplication has *very* serious issues and currently
breaks Pcbnew:
- No test is made, so a zone can be added to the same layer (duplicate zone
on same layers)
- No DRC performed on the new added zone on a copper layer (currently it
breaks the board).
- The new zone is not merged with existing zones (if any)
- The duplicate zone command cannot be undone.
- The filled areas are duplicated, that is bad (filled areas are certainly
bad)
Jean-Pierre,
Ok, the duplication clearly needs more work. I'll look into it.
I was actually (thinking about) adding support for a zone to exist on
multiple layers. However, it is exactly the zone testing, merging and
drc code that seem to be quite difficult to modify to take a
multi-layer zone into account. Basically, there are too many
zone->GetLayer() calls everywhere.

Duplicate zone is certainly a good feature and could be enough.
A multilayer zone is tricky:
For instance, many time some layers needs cutout areas.
How to handle cutout, or modifications (merging, priority level change) on only
one layer on a multilayer zone?
Having for instance a cutout on all layers is certainly unwanted.
Merging zones with already existing zones on a given layer is also tricky.
