Store board information beside sketch

[tobiasschuerg]

It would be nice if arduino would create a project file in the sketch directory so that I don't need to manually change board setup each time I switch projects.

I actually used the search, but "Autoselection of device" is nothing close to what I searched for. But thanks for linking.

IMO the most simple way would be to hardcode-config the targeted board type by configuration in Sketch (e.g. #pragma config...) such as
#pragma config board="Nano"
#pragma config board="NODE_MCU 1.0"
#pragma config board="Adafruit Feather ESP32"
