**WARNING**

  This demo might not work as expected and some documented features might be
  missing.

-------------------------------------------------------------------------------

This shows the three different types of editor that can be applied to a list
of objects:

- Table
- List
- Dockable notebook (a list variant)

Each editor style is editing the exact same list of objects. Note that any
changes made in one editor are automatically reflected in the others.
