In Dreamwaever there was a Design View for the CF document. This view was helpful to visually look over the long pages to find elements you are looking for. For example, you might have a form with 100 fields and the Design View allowed you to quickly select any field visually. Is there a similar functionality in CFB2?
No there isn't. There is a preview option. At the bottom of the editor pane, you should have buttons to preview in a browser. You will need to have a server set up and associated with your project.
