This is interesting because it should allow experiments with instances of LayoutMorph and 
LayoutSpec.

I tried installing on Cuis 4.2-2203 rather than 2198 per the ReadMe because that's what was 
handy. This is on a PC running 'Doze 7. Trying to use the ReadMe to install was not 
successful. However, from File List I did install the package. 

Not sure what you mean by option-click but button3 and cmd-button3 do the same thing: 
bring up the halos. The menu has your items at the end.

Tried edit Layout on LayoutMorph example2. Changed from row to column, clicked update 
and the change took place but the editor quit.

Could the way I installed cause this behavior? This has real potential and I'd like to see it 
working better.
