Sounds like a great idea. DJ do you have anywhere to host a
'suggestions' list for improvements/etc? Should integrate with bug/issue
tracker really. Perhaps we need to think around this area if launchpad
doesn't serve us efficiently.

Marvin - I fear it's probably not a trivial change to make, particularly
as you're not going to be referencing files between the programs. Nets
would work fine, but I think gnetlist does the "calculation" so gschem
hasn't defined the nets/doesn't know what/where they are. Typically when
I highlight a pcb trace, I'm looking at the netlist in pcb to see what
devices they connect (or should connect) to. It is very difficult to
back-annotate changes at pcb level to the schematic in my experience ..
you always have to work in the schematic and move through the
gnetlist/gsch2pcb chain.. or at least that's the only method I've found
to work.

Best regards,

Michael.
