Customize CreateDiv (Create div container) panel

Hello,

Whith CKEditor 3.2 :
Is it possible to not display "Advanced" tab of the panel CreateDiv (Create div container)?
I try this : config.createdivShowAdvancedTab = false;
This does not work.

Is it also possible to not display the form field "Stylesheet Classes" from the "General" tab of the panel CreateDiv?

And finally, is it possible to force writing the tag <br> after the end tag </div> when using the createDiv button?

Thanks for your help!
