Yes, to the degree that an editor must. Perhaps not to the degree that =
you would like. Perhaps more than I like, although now that I know to do =
(net-selection-mode "disabled=94).

I haven=92t had that problem. Perhaps more troublesome is that gschem =
has no notion of what a project is (and without that, refdes isn=92t a =
rigorous identifier), although I=92ve also *exploited* that ignorance =
from time to time. A plugin that implemented a model of a project could =
be useful. It wouldn=92t force that model on you. I don=92t think I=92d =
ever want to use a singular model for all projects: there are matters of =
scale and product that differ.

It=92s OK about named nets. Anonymous nets are a more interesting =
problem. As I=92ve said, I=92m interested in stabilizing their names in =
gnetlist.

I think it=92s difficult to mix scripting languages in a single tool, =
although Roland thinks he can. You should look into Xorn.

an user provided addon. This core should try to speak the same language =

gschem fails on this. It probably could be worked around with endless =
streams of scheme scripts, but it'd be easier to admit it and come up =
with a proper fix in the core.
So, you want a new tool with a different scripting language. Fine with =
me.
