IDEA: An Easy Way to Help to EQ by Frecquencies on Instrument's Images Selector

HI, first i say sorry for my english, i'm learning yet, i'm from Argentina.

My idea (I don't know if this idea is old or if another user posted befere) is:
In the superior (top) of quadcurve ecualizer (pro channel in platinum) its appear a keyboard with Notes and Frequencies.
 
So, i think that you can add an selector option to see the old keyboard or change for an image of varius instrumets with his particular frequencies like Piano/guitar/vocal/etc..
 
An image to figurate it: (see in the bottom, it show the tips for the sound too)

 
with an image in the top of eq, for the diferent sounds that indicates the ranges of each instruments and tips for sound i think that this tool will be very useful for a lot of people.....
 
 
thanks for the time, and i aprroach to send to all the Sonar's Users my cheers....
