title: View file structure in VS Code
body: <p>One of the features I use frequently in PHPStorm is the Structure window, which shows me my file structure broken down into functions, classes, variables, etc . I'm checking out VS Code, and I don't see an option for that type of window anywhere. Is there a similar window, or other way I can view the structure of my file?</p>
  
  <p>Thanks.</p>
