New tools and new plug-ins are great. We have a transparent schematic format and powerful scripting mechanisms to give us power and to allow us to keep that power from interfering with each other’s objectives.

We could prototype it via a plugin but in the long term it should
really be in the core. To be honest I find your "don't touch the core
you will break something" attitude kind of insulting. I am not out to
change how we have kept the concept of connections in libgeda and nets
in gnetlist. I just want to mirror the flat net model that already
exists in the core with a more nuanced and yet to be decided
structure.
