Great, as I said, we should name it  
HTML::FormFu::Element::ExtJS::Panel, so we don't clash with any future  
element which comes with formfu.

I think that's fine. The end user will not notice and we have a clear  
structure which will not clash
with formfu elements.

I'd say Panel should provide nested_name, too. I can think of forms  
where you want
to display a belongs_to rel in an extra tab, e.g.

This won't be a problem if we agree that Panel should have a  
nested_name, too.


Thanks for your thoughts on that!
