I believe that examples of this family of multi-column morphs can be 
found in Celeste and in the Enhanced IRC Client.  The 
PluggableMultiColumnListMorphByItemWithHeader is used by the enhanced 
IRC client.  Check it out on SqueakMap.  Also, when the multi-column 
stuff was created the first "client" to use it, that I remember, was 
Celeste, and then the other variants became used/created to support the 
enhanced IRC client.

I haven't looked at that code in ages.  It would not be a surprise to 
find that it may be a good candidate for some general refactoring.
