Make the Status, Visibility, or Date fields opened by default in the Publish box

This jQuery code seems to work, when added via the admin_footer hook.

• #submitdiv = the whole Publish metabox
• .misc-pub-section = each UI section (except the Publish and Save sections)

• .hide-if-js = the fields that are hidden by default

  $('#submitdiv .misc-pub-section')
      .has("#post-status-display, #timestamp")
      .find('.hide-if-js')
      .toggle();
  

That will unhide the Status dropdown and the Date picker.
