Thanks again. Looks like EasyEDA is a good tool. Again I'm just concerned if JLC stops supporting EasyEDA. That would mean I need to pick a new PCB software again but chance is pretty low I think.
I think it's extremely unlikely that JLC would discontinue EasyEDA - it's a strong tie-in to JLC, their assembly service and LCSC (a sister company).
But in any case, EasyEDA will help teach you the basics of PCB design and the process of laying out PCBs. With a solid background, changing software packages wouldn't be too onerous.
