Re: gEDA-user: Hiding individual layers of a layer-group

   I was already running pcb+gl - so that was a very fast fix. I didn't
   know about thin-draw :P
   I still think it would be handy to be able to turn of individual layers
   regardless of whether they are grouped though...

     How about some middle ground compromise - let it switch the layers
     for the purposes of selection / rendering etc.., but still draw a
     (or de-saturated) version of their contents to aid not drawing
     which would clash with other (hidden) sub-layers in the group.
