Currently we do a Gdk.Beep when a new window can't be opened in response to a middle click, but there's no visual feedback that the action was rejected
Proposal
We should do a little shake in addition to the beep to make sure there's visual feedback that the task can't be completed
Prior Art (Optional)
We use a shake in other places like the Lock screen and Polkit dialog to indicate input was rejected
