On the throttle (and rate curve), show the current value based on RC input

Would be awesome if the configurator offered the current throttle output or rate on the curve plot based on the RC input for that axis.

On Betaflight, I fine-tune my throttle curve by noting the throttle % in my OSD under different conditions. I I then open up configurator and adjust the mid-point and expo to get the desired throttle % at preferred stick deflections.

The only reason I ask for the same on rate curve is the documentation on the actual curve calculation seems sparse. It looks like actual rates with some pre-defined center value?
