On 27 March I complained about the Arduino IDE 2.0 RC5’s inability to edit URLs to point to board support repos ( /2022/03/27/a-problem-with-the-arduino-ide-2-0-rc5/ ). It appears that the latest release candidate has fixed this major problem. The only complaint I have left is how the ‘Cancel’ and ‘OK’ buttons are arranged. They are still opposite, and they are visible that way (see below). Oh well, at least I can begin to test the usage of the version 2.0 IDE with programming ESP32-S3 and ESP32-C3 development boards.
