title: Set extbase Controller Action in plugin
body: <p>I have set up an extbase extension in a TYPO3 4.5 site with the extension builder, containing just the default listAction in the controller.</p>
  
  <p>Now I would like to add a new Action, and it doesn't work.</p>
  
  <p>I don't need (aka. can't get to work) a flexform to choose the controller action. </p>
  
  <p>As there's a field "Plugin mode", I thought I could just manually enter the action here:</p>
  
  <p><img src="https://i.stack.imgur.com/ddKxU.png" alt="typo3 plugin mode"></p>
  
  <p>And extend the plugin configuration as such in ext_localconf.php:</p>
  
  <pre><code>Tx_Extbase_Utility_Extension::configurePlugin(
      $_EXTKEY,
      'Pluginname',
      array(
          'Controllername' =&gt; 'list,listfeatured',
      ),
  );
  </code></pre>
  
  <p>Also, in the controller, I have added a new action.</p>
  
  <pre><code>/**
   * action listfeatured
   *
   * @return void
   */
  public function listfeaturedAction() {
      // do something
  }
  </code></pre>
  
  <p>But, alas, the action is not called at all.</p>
  
  <p>Did I interpret the field "plugin mode" wrong?
  Did I miss something?</p>
  
  <p>Alternatively: Can I set the action for a "backend" plugin via TS as well?</p>
