Regarding jumpers/zero resistors. Is there a way to specify a custom symbol of jumper or 0 ohm resistor?
If is set the 0 ohm resistance, simulation complains.
If I replace it with <jumper>, then it looses the ability to be rotated horizontally and a header appears. Is it possible to have 0 ohm resistor that is handled by simulation or have a normal resistor symbol for an optional jumper?

maybe I can customize jumper appearance to look like a resistor?

schPinArrangement may help!

i think we can also fix the simulation to support 0ohm resistors (CC <@778624824875941908> i'm going to attempt this)

maybe I could just use normal resistors and set 0.01 Ohms

it's just they wouldn't be visually distinct

Thats essentially what we’ve implemented

It should go live soon

The minimum ngspice resistance is iirc 1e-12
