I'm using a board that can be programmed via Arduino IDE (a NodeMCU with ESP8266) and I've configured the Windows client successfully. I've added an additional board through "Preferences" menu by specifying its configuration url, following manufacturer's directions.
Now, I'm quite happy with the web editor, the one at create.arduino.cc, and I'd like to use it with this board too. Is there any way to configure additional boards?
