title: Drupal 8 - Change position of the Save Preview Button in a form
body: <p>I'm using Drupal version 8.6.10 with the default Bartik theme.</p>
  
  <p>I created a new content type called Post and I would the change position of the "Save" and "Preview" buttons of the form used when creating a new Post.</p>
  
  <p>Actually these buttons are shown immediately after the Title as you can see in the following picture:

  <p>Instead I want them to be shown at the <strong>end</strong> of the form.</p>
  
  <p>These are the Post manage display settings:

  <p>I don't understand why this doesn't happen with the default content types provided by drupal (Article and Basic Page) but only with the content types I add.</p>
  
  <p>How can I change that?</p>
