title: How to edit Sidebar under Sphinx Alabaster theme
body: <p>I have the following <code>index.rst</code> file.</p>
  
  <pre><code>Know the cell population of your data
  =====================================
  Some content
  
  .. toctree::
     :maxdepth: 2

  ~~~~~~~~~~~~
  .. toctree::

  Indices and Tables
  ==================
  * :ref: `genindex`
  </code></pre>
  
  <p>Now the sidebar looks like this:</p>
  
  <p><a href="https://i.stack.imgur.com/fbvUm.jpg" rel="noreferrer"><img src="https://i.stack.imgur.com/fbvUm.jpg" alt="enter image description here"></a></p>
  
  <p>As described in that image. I'd like to do couple of things.</p>
  
  <ol>
  <li>remove the title <em>only</em> in the sidebar but maintaining it in the main page. </li>
  <li>add new URL link, but not showing it in the main page like "Indices and Tables"</li>
  </ol>
  
  <p>How can I do that?</p>
