alt Hacker News> Why are you not using this through KiCad? That's what I would expect an amateur to do; especially since they handle the UX that you are complaining about.
They sound like an amateur at circuit design, not software engineering (which is how I'd describe myself too).
KiCad is still the preferred interface.
The original point stands. Ngspice shows its heritage from the days of Fortran far more than a modern code base would or should. It's sole great virtue (from my point of view) is that it integrates with KiCad and only falls over with no reason about 5% of the time.
I would suspect that some of the simulation systems coming out of the Julia community or Xyce would be a better base.
