Show Fan Speed on Info Screen?

Anyone know of a setting in Marlin to show the Part Cooling Fan Speed on the Main (Info) Screen?
I realize there is no much room, but for me, showing X & Y coordinates is pretty useless as the latency is so great, the print head is already somewhere else.
So I think it would be nicer to just replace that with Part Cooling Fan Speed.
Thanks!

I had a look at my relatively old version of Marlin and could see no such option. I doubt it has been 'added' since.

So I would say no, there is not such setting.

Do you understand C/C++ (or any programming language really)? I ask because you could set this yourself. It depends on which LCD screen you are using and so on.
For me, on a RAMPS1.4 board with the reprap discount screen I can edit the

lcd_implementation_status_screen

function to do such a thing. I am not sure if the
part cooling fan variable is visible to that class, but that is a simple problem to overcome.

Hope this helps.

Thanks!
I found the functions in ultralcd_impl_HD44780.h and replaced the "draw_axis_value(X_AXIS..." with my own function for displaying the Fan Speed "_draw_fan_status(0, fanSpeeds[0], blink" and it complies. Haven't loaded and tested it on the printer yet. It's hardly production worthy at this point.
Thanks again!
