Thanks Richard, I'll submit an additional note.

I agree that these are useful changes, in fact the reason I got into  
the resizing issue is because of custom control I designed as a group  
for my own app.  It would just be so much better if changes like this  
were documented in the dictionary.

I had noticed the selectGroupedControls property in the inspector  
window but thanks for mentioning that too.
