Really like this online tinkering idea, however it seems a bit basic. I can not find any CD4xxx devices at all. This makes digitally controlling analog signals impossible.
Please add 4000-series cmos devices and the 45 series as well. It would also be nice if the end user could create his own components, as I doubt you will add AD and DA
converters from the 70´s and 80´s to tinkercad.
