Swipe left/right to unindent/indent

Would it be possible to either develop a native feature or create a plugin that would allow you to swipe a bulleted line left to unindent and right to further indent? It makes it much more intuitive to create outlines or quickly reorganize on the fly.

Example:

  • Item 1
    • Item 2
      <—- Swipe
  • Item 3
    (Swipe) —>

Results in

  • Item 1
  • Item 2
    • Item 3
