     4- Why we’re doing this
     5    - Web apps don’t have access to system undo
     6        - Hidden content editable
     7        - Devices with no keyboards
     8- UI screenshots for content editable
     9- What we expect to gain
     10    - Usable Undo
     11    - Multiple Undo Stacks
     12- API
     13    - UndoItem
     14        - undo
     15        - redo
     16        - label
     17    - UndoManager
     18        - item(n)
     19        - position
     20        - length
     21        - addItem()
     22        - undo()
     23        - redo()
     24    - Element Extension (multiple undo stacks)
     25        - undoManager
     26        - undoScope (set the undoScope, creates undoManger)
     27- Undo Example
