title: How do I find the welcome screen in VS Code after I've closed it?
body: <p>VS Code doesn't seem to look quite the same as in the intro video I watched. The Welcome screen doesn't show the 'Customise' or 'Help' sections shown in the video that I watched... how do I get those?</p>
  <p>How do I find the Welcome tab once it has disappeared? How do I collapse the left sidebar?</p>
