How 'bout a check off box for completed tasks or "todo's"
This is possible but not described in the 2.1.1 manual:
1. Create a To-Do and give it a name, e.g. Shopping
2. At the bottom of the screen where you see a text entry oval, click on the + sign and add an entry, e.g. Cheese. Then add another entry, e.g. Milk.
3. Return to your Shopping To-Do list and now you will see Shopping as the title and below it, Cheese, then Milk.
4. Click on the box to the left of each item and a progress bar will appear at the top.
