I'd like the ability to add or remove breakpoints from a column container such that those edits propagate down to each child component.
If I delete a breakpoint from the props.breakpoints list property, I also have to (prefer to) delete those settings from each child component as well. I'd like that to be automatic.
Additionally, I'd like the "Column Breakpoints" section to:
  1. Update when the props.breakpoints property updates (without having to select a different component).
  2. Show an error (or reorder) when pixel sizes are not in ascending order.
  3. Explicitly support or not allow custom names for breakpoints.
