I just made the discovery the other day that there are two Arduino IDEs, the old crusty one maintained by Arduino.org and the new hotness maintained by Arduino.cc.

I'd been using the Arduino.org version which had mostly driven me to use PlatformIO and ESPHome.

Unfortunately, but perhaps fortuitously, I needed to use a Library only compatible with Arduino 3.0.0 which is incompatible with PlatformIO. That lead me to discover the Arduino.cc IDE which, while not on par with VSCode, is dramatically better than the Arduino.org IDE.
