As much as I love what they're trying to do here, I can't help but feel that they need to work on some of the basics first. For example, if the parts you're using don't already have a footprint, etc set up on circuits.io you're pretty much screwed. Design a pad by inputting vertex coordinates? Seriously? It would be much better if you could choose a general shape and tweak the parameters from there – vertex coordinates should be left as a last resort.
Props to the team, though. I hope this gets traction.
We are working hard on a better footprint editor right now. It will probably be released in one or two weeks. If you have trouble adding a footprint you can always send us an email and we'll add it for you.
