Kristoffer,

I was merely talking about getting your initial implementation correct
in Pcbnew to prevent issues with the full implementation down the road.
While I'm OK with opening up a full design specification, I think it's a
bit premature and will distract us from the immediate work at hand.
None of the schematic group linking work can happen until the new
schematic and symbol library file formats are complete.  I want to keep
the focus on grouping in Pcbnew for the time being and not get bogged
down in a full implementation specification.

Cheers,

Wayne
