title: Intellij - Split Screen Creates Duplicate
body: <p>When I have two Java files, and I want to compare them side-by-side, I split them vertically.  However, I end up with 3 Java files, because it duplicates the one I split, instead of just moving it.</p>
  
  <p>Is there a way to change the behavior such that it just splits the two files I have open, rather than creating a 3rd?</p>
