I want to remove tabs(invoice,credit memo,shipment) in sales order view using observer
My config.xml file

    <adminhtml_widget_container_html_before>
                        <observers>
                            <package_test_adminhtml_widget_container_html_before>
                                <class>test/observer</class>
                                <method>adminhtmlWidgetContainerHtmlBefore</method>
                            </package_test_adminhtml_widget_container_html_before>
                        </observers>
    </adminhtml_widget_container_html_before>

My observer.php

public function adminhtmlWidgetContainerHtmlBefore($event) 
    {
        $block = $event->getBlock();
        if ($block instanceof Mage_Adminhtml_Block_Widget_Tabs) {
            $block->removeTab('order_tab_info'); // I am trying information tab from sales order view but it doesn't work          
        }
    }

Try this:

In config.xml use core_block_abstract_to_html_before instead adminhtml_widget_container_html_before

<events>
    <core_block_abstract_to_html_before>
        <observers>
            <package_test_adminhtml_widget_container_html_before>
                <class>test/observer</class>
                <method>adminhtmlWidgetContainerHtmlBefore</method>
            </package_test_adminhtml_widget_container_html_before>
        </observers>
    </core_block_abstract_to_html_before>
</events>

and replace your observer adminhtmlWidgetContainerHtmlBefore() with:

public function adminhtmlWidgetContainerHtmlBefore($event) {
    $block = $event->getBlock();
    if ($block instanceof Mage_Adminhtml_Block_Sales_Order_View_Tabs) {
        $block->removeTab('order_transactions');   // Remove tab by id
        $block->removeTab('order_history');        // Remove tab by id
    }
}

Note: Please don't try to remove sales order view current active tab, it will thrown below error:

PHP Fatal error: Call to a member function getId() on a non-object in /var/www/html/magento/app/code/core/Mage/Adminhtml/Block/Widget/Tabs.php on line 236, referer: http://127.0.0.1/magento/index.php/admin/sales_order/index/key/47b8c63b239bfb55d90a12088f642fed/

Magento – Save admin name to order_status change using an Observer

EDIT:

You can also do the following, which I would recommend over the previous solution I posted. Mostly because it doesn't use setPost, which I would consider scary.

config.xml:

<adminhtml>
  <events>
    <sales_order_status_history_save_before>
      <observers>
        <module_status_history_save_before>
          <class>module/observer</class>
          <method>commentSaveBefore</method>
        </module_status_history_save_before>
      </observers>
    </sales_order_status_history_save_before>
  </events>
</adminhtml>

Observer.php:

public function commentSaveBefore($obs) {
    $event = $obs->getEvent();
    $status = $event->getDataObject();
    $status->setComment($status->getComment().$this->_getAppend());
}

protected function _getAppend()
{
    $admin = Mage::getSingleton('admin/session')->getUser();
    $username = $admin->getUsername();
    return " : " . $username;
}

This would accomplish the same thing, except you're intercepting the model before it gets saved, allowing you to alter the comment without having to use setPost().

Original Post: You could do the following:

config.xml:

<adminhtml>
    <events>
        <controller_action_predispatch_adminhtml_sales_order_addComment>
            <observers>
                <module_order_save_comment>
                    <class>module/observer</class>
                    <method>adminhtmlSavingOrderComment</method>
                </module_order_save_comment>
            </observers>
        </controller_action_predispatch_adminhtml_sales_order_addComment>
    </events>
</adminhtml>

Observer.php:

public function adminhtmlSavingOrderComment($obs) {
    $event = $obs->getEvent();
    $order = $event->getOrder();
    $data = Mage::app()->getRequest()->getPost('history');
    if ($data && isset($data['comment'])) {
        $data['comment'] .= $this->_getAppend();
        Mage::app()->getRequest()->setPost('history', $data);
    }
}

protected function _getAppend()
{
    $admin = Mage::getSingleton('admin/session')->getUser();
    $username = $admin->getUsername();
    return " : " . $username;
}

This should work for you.

Magento – Adding Button to Sales Order View Using Observer

In your config.xml you have a <global> node however that is never closed out add </global> before <adminhtml> and it should work everything else looks OK to me.
