Yes.. I noticed ;)

Perhaps some heuristic to suggest how the user "fixes" their stack-up
would be possible (once support for saving layer colours in the PCB file
is present).

The problem is not over with ordering of layers though. There is also
the need to define the thickness of each piece. Special layers, like
"outline" which might appear in the "stack" need to be ignored, or given
a notional Z-coordinate too.

Best wishes,
