Oh yes, I've read Squeak By Example and played around with Morphic a bit
(although haven't created anything useful with it), I just need to figure out
how to write a class that I can use as a "model" with Morphs such as
PluggableListMorph.

Aidan,
A "model" is the logic of your program. Generally, it is the abstract concept that your UI
attempts to present to the user. For example, if you are creating a personal finance
program, your model might consist of objects like BankAccount and Transaction, whereas
your UI might consist of BankAccountView and TransactionView.
"Model" is one third of the time-tested concept of Model-View-Controller, which is a
"pattern" for creating programs with user interfaces. If you search for MVC on the web, you
should find some pretty useful information. Generally the theory behind MVC is that your
application's logic (or model) should be separate from its interface / presentation (view). The
controller would be some "glue" which mediates between the model and the view, but often
the controller is sort of melded into the view these days.
Squeak does include a class called Model, which is abstract and not much used these days.
Best not be distracted by it.
Hope that helps! Have you looked at some of the great Morphic tutorials on the web? I
found the chapter in Squeak By Example very informative.
