I don't know whether the Amiga software to which you refer does this, but
one of the things I have not gotten around to trying is a detail brush that
you rub on areas you want to be more detailed.  This could also be a lasso,
of course.  This would enable people to make decisions like "I need a little 
bit more detail over here" or "I need a lot more detail over here."  The
effect on the histogram could be cumulative.
