So I figured out that this is a Designer issue, not Creator since 
Creator only builds a plugin that load Designer. Cross over to 
development list.

After diving into Designer source, I find out I need the have a 
so-called "buddy marker" which is a '&' in the label text. After 
including that, the buddy checkbox automatically checked.

I can't find any mention of the "buddy mark" anywhere. Why do we need 
that in the label? And why does buddy check rely on it? I can still 
specify buddy relation with buddy edit mode WITHOUT the marker in the 
label. So why is it required?

And if it's required for good reason, the buddy check box should be 
disable since it's always linked to the existence of the marker.
