It would be nice if you could remove unwanted fields in form builder. For example I was building a form today but asked for too many fields, I soon discovered that I didn't need as many as I thought, but the only way out of it was to start over. It would great if I could have deleted the ones that I didn't need.

Also, the same happens if you try to add fields to the form, the only way is to start from scratch and that is a time consuming chore.
