title: VSCode: Open files NOT in a new tab, reuse current tab
body: <p>I believe that this is not covered by the Preview feature. I simply want to open a file for editing via Quick Open (or any way?) and replace the contents of the active tab, closing the open file and replacing it with the new one.</p>
  
  <p>This behavior is central to the way I edit. Currently, I'm always opening new tabs that I don't want. It's the only barrier left between Code and the way I've used Vim for 15 years. I imagine that this is scriptable, but would like to avoid going down that road. Please tell me I'm missing something.</p>
