I think the existing equalizer effect does just fine.  What would
"graphical-equalizer" do that the existing doesn't?  The only thing
I see is it would have a fixed Q/bandwidth.  I'm failing to see and
advantage in that...  You could just set the Q at 2 for all of them.

White noise requires time for the random nature to settle on an
average of flat.  A frequency sweep can be quicker and more
accurate.

For viewing, I often use baudline, a powerful signal viewing tool.

Yeah,  I'd like to have a plot of all the steps in the chain.  I
don't see how your proposed "graphical-equalizer" effect would make
it obsolete, though.  Oh - unless as a single effect it takes
multiple frequency/gain pairs.
