I have an IR touch frame installed on my monitor. I found it took some getting used to but use it a lot now for any of the switches in particular. I have even used it to use the throttle quadrant, when flying twins, to grab and drag individual levers. Works fine for practicing engine out procedures.
I am still using my old sidewinder, that only has the one throttle axis, and legacy keyboard assignments for prop and mixture, so individual engine control is a pain without the touch screen.
