Need new tab that contains only vetted parts. As a designer I do not want to mess with other peoples objects that I have no faith in unless there is no such part. At a minimum these vetted parts should be fully modeled privative, power supply AC and DC, resistors, capacitors, inductors, transistors, mosfet, NAND, NOR, inverter(logic), AND, OR, XOR. All the open collector version for the previous logic gates. All other parts can be built up from these primitives. Please look into this @Lance. I feel there is not much use for this tool without it.
