How does an Arduino Chrome web editor app running on a pc with Linux differ from a Chromebook? I ran it on the Chromebook, first. The Linux set-up was next. The ArduinoCreateAgent was needed be downloaded (again) and installed to connect with a Uno port on the Linux computer. In other words, two different times. I expected the Chrome web editor app to be, well, a Chrome app, but in both instances it appears to be a desktop app. I also have the IDE desktop app on the Linux pc.
What this appears to me to mean is that it is not possible to log-in to Chrome on a third computer, connect an Arduino board, and upload Arduino files without first downloading and installing a driver on the third computer. Is that a future prospect, like with other Chrome apps that reside on the Chrome browser/cloud servers?
