title: Fluidtypo3: Use custom field as title of FCE
body: <p>I don't want to use the default header in my FCE's, but only custom flux fields. In the backend list views my FCE's are shown as "[no title]" because the default header is not filled. This leads to much confusion for editors.</p>
  
  <p>How can I define one of my custom flux fields to be used as title for the FCE in TYPO3 Backend list views etc.?</p>
