I would love it if Dovetail would add a PZB release button to the PS4 controller. I do have a keyboard but when trying to click the 'end' key it moves me to the head out camera. (I click 'function' and 'right arrow') The only other way of clicking it is via the cab - which is annoying when in outside cameras and is also small and hard to click. I would suggest having the up D-pad up button be the PZB release as I have no knowledge of German trains having bells.
