Hi Nikki,
That's great usability feedback, thanks.  I'll look at those point now.  Re the role preview, yes it'll be interesting to see how users perceive this, or not....  :-) 

In regard to the other issues you've noticed.

Drag and drop. 

• The icon is in the top left corner of the element, it appears when you hover over the question.  This clearly wasn't obvious to you; perhaps because you didn't even understand that drag and drop was available there's no way you'd recognize the icon popping up meant that (even if you saw it in the corner of your eye).
  
• Help.  You're correct, this isn't mentioned.  I'll get that added.

The use of a scroll bar for long text,.

• This is a design decision to constrain the length of the form.  
• As an aside I've have noticed that the width of the text box is defaulted to 32 chars, which is too small.  Optimal reading is 70-100 chars, so I'll get that changed.
