Homepage example

1. On the to-do list example on the homepage, when I click a To Do to edit it... how do I "save" or "Cancel"? Seems like I should be able to remove the text input when I Tab or Enter... or click a cancel button.
2. Can we add a slide animation when the to-do is removed? Sliding it out to the left or up would simulate removing an option, rather than a hard display:none;

Start at the homepage to-do list example and reproduce both editing and removal flows. Check how editing is completed or cancelled and how removal currently hides the item; done means the edit controls have clear completion and cancellation behavior and removal uses a slide animation.
