title: VSCode: Prevent split editor to open same file left & right
body: <p>I'm currently using VSCode as my main editor, however, when I split the editor into 2, it opens the same file twice, like left &amp; right (see image below).</p>

  Is there any way to prevent it from opening the same file on the next editor? Currently, I have my custom settings and can be copied from <a href="https://gist.github.com/genesisneo/4e98d3c0ad1f3e634f474a32d36b9f12" rel="noreferrer">here</a>.</p>
