Add shortlink button to post page

In the most recent WordPress update when you post a new post it displays a sidebar on the left hand side which shows new targets, quotes and edit links. Despite being a far improved design one of the things that I used to use a lot was the ‘Get Shortlink’ button which allowed me to easily share to Google+. Instead I have to copy the link of the ‘Close Sidebar’ button which is significantly longer

I think that the ‘Get Shortlink’ button should be added to the sidebar as this was a useful feature.
