display ppm input in setup

Wile setting up the ppm input It would be very helpful if there was a readout for the current ppm signal of at least one channel.
this way if you do not know the proper ppm delta or center. You dont have to go between ppm setup and channel monitor to see if your settings worked correctly. You can just watch the current value and adjust acordingly
Not sure if this is the place for "ideas" but it seemed as good as any
