= Undo API
''by Megan Gardner''

- Why we’re doing this
    - Web apps don’t have access to system undo
        - Hidden content editable
        - Devices with no keyboards
- UI screenshots for content editable
- What we expect to gain
    - Usable Undo
    - Multiple Undo Stacks
- API
    - UndoItem
        - undo
        - redo
        - label
    - UndoManager
        - item(n)
        - position
        - length
        - addItem()
        - undo()
        - redo()
    - Element Extension (multiple undo stacks)
        - undoManager
        - undoScope (set the undoScope, creates undoManger)
- Undo Example

document.undoManager.addItem(new UndoItem({
	label: “MyAction”,
	undo: () => {
		// undo the action
	},
	redo: () => {
		// redo the action
	},
	merged: true
}));
