title: Adding plus button in WPF tab control after the last tab item?
body: <p>I would like to achieve the "new tab" functionality of web browsers in WPF. In essence, I want to display a button after the last tab item which upon pressed creates a new tab.</p>
  
  <p>I have no idea where to even begin. Should this button be part of the tab control or be out of it?</p>
