Wish List item: Feed back on Add ToDo item at end of Chapter 4

[mikeraz]

As it is now one types their text, clicks the button and the text disappears. A check of Newest shows the item added to the list.

Be nice to diplay " added to your ToDo list." Maybe even fading out.

My attempts to implement this functionality have been stymied by (it seems) scope issues. A var newItem gets unset before the content display.

Yes, this would be a great feature! I'm toying with the idea of making part of this repo include reader-created features/examples.

Once I get all of the examples from the book posted we can explore that in more detail!
