> what is the "references search"? Do you mean the message finder?

No, I'm referring to the function shown in your references-1.png
picture just above the red box.  Also invoked by Shift+Command+N.  For
when you browse references to a Class.

Invoking that function on a Symbol expression now appears to do
nothing.  So this would be a good place to fit your new feature into
the IDE.  It actually is finding and presenting references to the
Symbbol, so "References" fits very well.

I still strongly recommend use of the #flag: approach, however,
whereever "magic" implentations breaks message tracing.
