Re: PcbNew netlist updating codepaths
I've just done this small patch in my branch:
I may leave it alone there until the branch is merged and then the big
refactor can happen.
If you're excited about taking it on at that point, I'll leave it to you
since I have a few other running projects and don't want to juggle too many
