Good Todo is an online to do list that separates today's to do list from that of other days. This way you can focus just on what you need to get done today, without being distracted by a bunch of things that don't yet need attention.
Good Todo can help you empty your inbox. Just forward action items from the inbox to Good Todo, then delete (or archive) the item from the inbox.
This 3-minute video shows how to create a new to do, redate a to do to a different day, and create a new to-do via email.
