At the beginning of this month Ned Konz sent a change set with a 
connector morph to this list. Together with the recent additions by Dan
Ingalls (selecting multiple morphs and undo) Squeak is
now quite a nice mind-mapping tool. Over the more graphically 
polished versions of this kind of software it has the tremendous 
advantage that the map can be traversed programmatically be writing 
scripts.

Citation from a dissertation on concept mapping

Concept mapping is related to several distinct research areas, 
including knowledge representation (Sowa 1991), graph theory 
(West 1996), graph grammars (Cuny, Ehrig & Engels 1994), and 
hypertext (Conklin 1987). Each of these areas deals with graphs - 
nodes with arcs that interconnect the nodes. Each of these areas 
is relatively independent, and all tend to use different terms 
for very similar, if not identical, concepts. The term node in 
concept mapping is called a vertex in graph theory, and a concept 
in many sub-disciplines of knowledge engineering. The term arc is 
called an edge in graph theory, a relation in many sub-disciplines 
of knowledge representation, and a link in hypertext theory. 

Mind mapping is essentially the same as concept mapping. It is less
stringent on the relations used and encourages creativity in expression.
It has been popularized by Tony Buzan.

Hoping that this feedback might be useful for someone
