Arduino IDE for Chromebooks: The latest thread I've found is summer 2016. Any progress? Can it be done yet?

I agree it would be nice if the real IDE worked on Chrome OS but I haven't heard any word about official efforts towards that. The Arduino IDE is all open source so anyone is welcome to take up the project. Get to it!
