Adding button in sunstone

Hello Guys,

I want to add a button to opennebula sunstone UI. I am using my own seperate dns server and want to make a tab for my cloud group user to manage the dns for their vm’s. Can anyone tell me how can I add a tab (if not possible then a button) on the sunstone UI.

Thanks in advance

Got my answer from the documentation itself . Do not know how I missed it before.
