  <h2>Issues</h2>
  
  <ul>
    <li>Long labels could overlap on hover, particularly first/last items</li>
    <li>Labels can lose centering when there are many options or the viewport is too narrow to accomodate the required width</li>
  </ul>

  <h2>To Do</h2>

  <ul>
    <li>Highlight changes with red arrow</li>
  </ul>
