Many thanks Scott and John for taking the time to
reply, much appreciated.

I can't believe I overlooked the obvious! I was
thinking in terms of breaking it down into different
classes, but different categories of one class that
can all access the same instance variables is exactly
what I need. All I need to do is create separate files
that are categories of the MyDocument class, one
category for the table view and another for the
outline view, and so on. Then of course I will just
use separate controllers for diffferent windows, such
as a preferences controller for the preferences
window. (Thanks John, too - I forgot that by sending
the object with a notification I could access its
instance variables, very helpful.)

Many thanks again for clearing this up; this makes
approaching the large task ahead of gluing all the
parts together that much easier.
Keith
