title: Created my own viewsContainer - can I include views from other viewsContainers?
body: <p>We are exploring creating our own viewContainer for VS Code in a new extension and would like to re-use views from other containers, such as the Resources tree, Outline, and others from other extensions. Is this possible? </p>
  
  <p>I was unable to find the view ID for the Outline view, for example, but would hope I could do something like...</p>
  
  <pre class="lang-json prettyprint-override"><code>"contributes": {

              }
          ]
      }
  }
  </code></pre>
  
  <p>Is this possible? Is there a list of published IDs for established views in the VS Code environment that we could reference and re-use? </p>
