Custom hardware presets

[marecl]

I have encountered one of the biggest problems: developing code on two different boards at the same time. Every time I change board I must set everything up again so I've got an idea:

1. Every window with code can have independent board settings and Serial Monitor (SM wouldn't be critical but would be nice)
2. Save current device settings (like baudrate, COM port, clock frequency)

Or (somebody posted this before) add preprocessor command so device can be identified and configured "on the go" in the sketch.

At least on Windows and Linux, this is already possible. If you start two instances of the Arduino IDE (by starting the application twice), you can have a different board and port setting on each instance. This is different from the behavior of multiple open windows of the same IDE instance (which are generated from File > Open, File > New, File > Examples, and File > Sketchbook), where a Tools menu change on one IDE window affects all other windows.

I'd assume you can do the same on macOS but I can't check that. If someone discovers that is not possible on Mac then I think it would be reasonable to reopen this feature request.
