I really like the interface, and how it combines my to do list with my calendar in a user-friendly way. My appointments to-do list is in the same area!
Feedback I’d give is to have a way I’d be able to prioritize tasks. For example, you can have your big three tasks bolder, in a different color, or with a noticeable star next to them. Definitely have them on the top of the list for that day. Your other tasks would have the standard appearance in font).
