Yes,  originally I had the mode line displaying either "CHG" or "chg"
depending if the submide was active or passive.  (Those terms refer toe
the old version; I've now called the visible on invisible.)
But Richard Stallman said there was no point in having a modeline
indicator when in "active" sub-mode because it would be obvious.

So there are [in both the old and the new versions] two variables that
can be customized:

highlight-changes-active-string - defaults to nil,  but you could
                                set it to " CHG" for example.

highlight-changes-passive-string - defaults to " Chg".

I think that paragraph is still true.   Any changed text should have
been displayed differently when you turned on highlight-changes-mode
(even though the mode indicator hadn't changed).

 Also it might be a good idea to use
 > define-minor-mode to define highlight-changes-mode.

OK, I'll take a look into that.

Thanks for the feedback.
