Feature - Dependent Voltage and Current Sources (Diamond)
I find circuitjs1 very helpful in my learning of circuit analysis, but cannot find the traditional "diamond" for dependent voltage/current sources.
Controlled sources are available under "Active Building Blocks" but not the diamond notation, because that would require the controlled source element to be connected to another element and I thought that it would be hard to make a reasonable UI for that. Instead, controlled sources look like a chip, with the control voltage/current as input(s).
Actually we could have the voltage controlled sources refer to labeled nodes for voltage. And current controlled sources could refer to ammeters, which could have a label added.
