title: VS Code: Focusing the current editor
body: <p>Let's say I've got the following scenario:</p>
  
  <ul>
  <li>Program maximized with "Explorer" tab and 2 editor tabs open</li>
  <li>(i.e. on windows) I want to peek some website so I split half screen to the browser, half to VS Code.</li>
  </ul>
  
  <p>I want a hotkey that hides the explorer, reduces the size of the unfocused tabs and focuses the main editor tab. Does a think like that exist (or any addon does that?).</p>
