Once my project is complete, I will need to get PCB's made for the circuit. I heard about PCBWeb Designer. So I am playing with it, and discover it does not have a Potentiometer symbol and the Digi-Key Library excludes them. My circuits use Trimmer Pots. So is there a better program to be using? A solution to this problem? It also doesn't have 100k NTC Thermistors.
