Ability to switch to vertical scrolling

[guylepage3]

Is your feature request related to a problem? Please describe. It would be great to add the ability to switch to a vertical scrolling view.

Describe the solution you'd like It would be nice to either toggle a "Switch to vertical view" or supply a code snippet that would adjust CSS Flexible Box layout to a vertical scrolling view for folks adding a "To Do List" item for example.

    overflow: auto;
}
