Interesting. With X, Y and Z, spindle on and off, and feed

happy. If I add a 4th axis, I will add functions to jog the rotary

Be careful with that spindle on button. Consider the situation where you are doing a tool
change and the spindle starts due to the joy stick falling, something falling on the
joystick, or hardware malfunction.

The machines I deal with are enclosed with a door interlock system, your machine is open.

Yes, the cat or the kid pressing the button which you're wrenching the
QC lock wouldn't be good. I'd suggest that spindle start and stop should
be done with "hard" buttons mounted to the panel under the monitor, and
preferably the buttons with the raised collar around them so they are
bump resistant.
