Customize buttons on Day CQ pages

It is rather simple to customize buttons on http://cq-instance/siteadmin or http://cq-instance/damadmin etc pages for an individual user or a group. Customizing includes the removal/addition of buttons on the said pages. This can be achieved by manipulating the CQ5 Access Control Lists(ACLs) for the user/group.
Say group-A doesn’t require to activate, deactivate and workflow buttons on siteadmin/damadmin pages. 

To achieve this follow these steps:
1. Traverse to http://cq-instance/useradmin url
2. Select group-A from the left side menu
3. Click on the “Permissions” tab on the right side.
4. Traverse to /libs/wcm/core/content/siteadmin/actions/
5. Then uncheck the checkboxes(Read/Modify/Create etc) for each of activating, deactivate and workflow nodes.
6. Save the changes for the group-A.

The above steps can be repeated for disabling buttons for damadmin or welcome page or tools pages etc.
