Thank you very much for your interest ! It looks very cool !
I had started working on some basic elements for resistors and capacitors but I haven't taken the time to finish it
Could you make this into a pull request ? I'll try to take a closer look ASAP

I would do a PR but I need assistance, where did you put the resistors and capacitors, quick question as well, how are you supposed to caption your elements?

You can take a look at the comp/electrical branch where I've added resistors and capacitors

how are you supposed to caption your elements?

What do you mean by caption ? Do you mean like the name displayed in blocks or extenders ? If so, that would be here :

src/elements/element.typ Line 127 in 2bb7e3b5a9
if (name != none) {
