Most music applications have a feature called “MIDI Learn”, where you basically click any parameter, turn a knob or push a button on your controller, and it binds that input to the parameter. It’s amazing and allows for the creation of complex, expressive workflows.

I wish that this was a feature throughout the OS. Being able to bind a foot pedal to pasting from the clipboard, or a slider to a variable in your IDE, or a rotary to a control in a video editing app, would be amazing and open up entirely new avenues for computing and letting people customize their setup. Particularly thinking of the accessibility implications.
