Indeed it is.
My concern about canvas is that it does not convey a relationship to our

to refer a full layer or even to a stack of layers. IMHO, it would be

orthogonality. The top/bottom magic are
I suspect that in the main GUI you'd get a simplified set of options,
like add layers or remove layers to switch from, say, 2-layer PCBs
to 4-layer PCBs, etc. Outer special layers like silk and mask just
exist, but you can enable/disable them.
So most users just see one copper drawing layer per
I apologize in advance if this has already been suggested somewhere in
this thread, but one thing that I've thought about footprints while
reading the thread is keepouts.
Allowing for putting keepouts in the footprints is a very important
addition to whatever gets decided, but what about
I think the term you're looking for is a courtyard - the part of the
PCB's airspace that's owned by the component.

Most places handle this with the assembly layer.
Of course, this wouldn't be part of DRC, but you'd have to be blind
put stuff overlapping assembly layers and not see it right away.

Gah, you perhaps saw my comments on geda-dev about that. I've got half a
mind to bulk rename as appropriat:
max_layer - max_copper_layer
OR- max_group
They happen to be the same number, but the context is different
Having said that, I'd do you one step further, and move /all/ the
layers into their own list structure. Each layer would have flags
set to indicate if it was a copper, silk, keepout or virtual (ie,
ratsnest) layer. They would also be tagged as being always on top or
always on bottom, in the

It's a PITA to find and read the geda-dev archives, and given the relatively
low volume, I don't usually bother. So I missed your comments.
If you're developing, ask Ales to get you signed up to geda-dev. As you
say, it is pretty low
