Hi,
Thanks. Your suggestion sounds better. I meant a very basic tool with maybe 30 of the most typical active and passive components, a sort of drag and drop/insert smiley thing: a V+ and V- and ground symbols, a DC and an AC voltage source symbol, a current source symbol, and a rudimentary way of drawing wires/connections that isn't infuriatingly bad. Something to explain a basic idea with only a few components and also to prevent those criminally awful crazy spaghetti pen drawings one or two people do (especially one person I'm thinking of). The wires would be hard to implement, presumably. Anything more complicated would be better done on personal choice editor and uploaded as jpg or png, as you said.
