[Antennas] How do you use an antenna tuner?

I like this.  Now can it be made so that a seriues of idiot lights are 
used, say red, yellow, orange, and green.  Green being the best, set up 
with the tunning current.  The other one that I have seen but need 
schematic is the similar series for VSWR indicator.
