Really, really nice! I made it do a thing! https://misc.c4757p.com/kicad_sim.png

I feel bad to provide a bug report on my very first communcation on
this, but... found one: not sure if this sort of thing is actually
standard SPICE or an LTspice extension, but I tried parameterizing a
component value, setting a resistor's value to {R} - that sort of thing
leads to irrecoverable lockups here.
