    editor: start on new document button
    
    Now that all the features are in Dazzle for this, we can simplify things
    here. We still have a bunch of style tweaks to do, for example, the
    design calls for the button to be closer to the perpsectives button.
    
    Also, the styling of the menu is still a bit off.
