Arduino Create (AKA, Cloud IDE)

I can see s subscription IDE in the future, similar to the "success" of Adobe products.
But, most of my work is on ESP boards like the Wemos D1 Mini, the NodeMCU, etc. I can't recall the last time I developed anything on the Uno or Mega.

So, does anyone know if the 8266 boards will be supported on the cloud IDE?

They are not supported right now, but ESP8266 support has been requested many times so Arduino is definitely aware this is something people want very much.
