I just wanted to feed back that I was using the library part for the Adafruit Huzzah ESP8266 breakout board until I discovered that the pin spacing (across the board width) was too large, the part uses 900 thou but it should be 800 thou.
I went here to the Aadfruit site
https://github.com/adafruit/Fritzing-Library/blob/master/parts/Adafruit%20HUZZAH%20ESP8266.fzpz
to find their part which has the correct pin spacing.
If someone could update the Fritzing library with either a correction to the existing part or the Adafruit part that would save the next person some trouble.
Am impressed with Fritzing and enjoying using it!
