Create as many lists with as many items as you need! Check items off as you acquire/complete them. The values of any item you add can be saved for future reference.

Add a single item or add another existing list! Adding another list comes with three options:
1. Add all items as unchecked
2. Add all items as is
3. Add only unchecked items

Backup your data and keep it safe in a directory of your choice. Restore your data at a future date!
