Hide 'configure block' for Omega theme?
If you are using Omega theme version 7.x-3.1, you can go to the templates folder and edit region--content.tpl.php. In line 12 you will find the following:

   &lt;?php if ($action_links): ?&gt;&lt;ul class="action-links"&gt;&lt;?php print render($action_links); ?&gt;&lt;/ul&gt;&lt;?php endif; ?&gt;


You can comment this line out, or delete it.
