Let's say (purely hypothetically, of course) two identical toy turntables and a joystick. Could we overload this to .open(string name, int id) for such cases?

Yeah, that makes sense.  I guess it wouldn't be bad to have .countNamed(string name) or something liked that to tell you the number of devices with "name", so you know the range of id in .open(string name, int id).  Right now open(string name) just opens the "first" one it finds, which I would expect to be pretty arbitrary and inconsistent.

Could we also get this for the MIDI abstractions?

Yup, this is in the works for MIDI also.

Hence; I implemented basically this for the MIDI devices (so Windows can swap stuff around if it feels the need),  I think .name(string) would make sense there too.
