Where is the template for the promoted to front page items?
This is tipically done in node.tpl.php in your theme. Just keep in mind that this template works for any node, so you should introduce some logic to check if the node is promoted, e.g.

&lt;?php if ($node-&gt;promoted) { ?&gt;
  &lt;i class="icon-menu"&gt;&lt;/i&gt;
  &lt;div class="something"&gt;Maybe some other stuff&lt;/div&gt;
&lt;?php } ?&gt;
