So you’d like users of your extension to know which version it is, so you can give them support, without asking them to open extension files?

In your helper add this method:

public function addAdminhtmlVersion($module)
{
    $layout = Mage::app()->getLayout();
    $version = (string)Mage::getConfig()
        ->getNode("modules/{$module}/version");

    $layout->getBlock('before_body_end')->append(
        $layout->createBlock('core/text')->setText('

<script type="text/javascript">
$$(".legality")[0].insert({after:"'.$module.' ver. '.$version.'<br/>"});
</script>

        ')
    );

    return $this;
}

And in your controller action, add the method call:

// ADD:
Mage::helper('yourhelper')->addAdminhtmlVersion('Your_Module');
// BEFORE:
$this->renderLayout();

Now on admin pages that were introduced by your module it will show “Your_Module ver. 1.2.3″ right above the Magento version.
