Hmm...  That does explain why when people are complaining that they
are complaining about the db tree view and not the "main" view.  (Main
in IMNHO since the regular report display is the one I use.)

Well...  That does create problems for my suggestion then.

Agreed.  Now that I learn this.

Yes.  But I have yet to see anyone actually complain about those.
(It's possible I have missed seeing a complaint.  But I don't recall
having seen one on the mbox archives.)

Right!  The Streisand effect.  The very act of trying to suppress
something calls attention to it.

Even better John Oliver did a (tremendously humorous but very
irreverent, NSFW due to language) report on this topic too.

Usually it is better to let sleeping dogs lie.  Otherwise attempts to
suppress information will only serve to call attention to it.

My best advice to people is to do nothing.

Okay then!  I'll look at it.  Won't be today.  I'll put it on the task
queue.  Good that I see it is in Perl as that is a good language for
me.  I don't see where address hidden is done there but I am sure it
will become clear when digging into it.
