More GPIO accessible for SonOff Dual and TH10/16

If, on the next version of the circuit board for this and others, if you put header pin holes or even just small solder points for the other GPIO's, such as 2,4,9,12,13-16, I would buy a dozen more...   right now, trying to solder a 30ga wire to the straight to the ESP8285 chip is the only way and it is risky and looks unprofessional.

 I think these could become the favorite of IoT hackers... you can have one-wire or RTD via SPI, flowmeters, switches, etc run on this great board that already has a line voltage power supply and two power relays on it..
