My team is trying to replicate in one of our views how Canvas presents TODOs in its own UI. The TODO items endpoint (https://canvas.instructure.com/doc/api/users.html#method.users.todo_items) appears to be the correct one to use, although it's unclear what parameters Canvas itself may be using to for its presentation. As such, we have some questions about Canvas and the API.

When Canvas presents the TODOs in its own UI, what rules/boundaries determine the list of items that are being presented:
1. Does it present the user's most recent n number of TODOs?
2. Does it present the user's TODOs for the current term?
3. Does it present all of the user's TODOs ever?
4. Something else?

Regarding the TODO items API (https://canvas.instructure.com/doc/api/users.html#method.users.todo_items), we're trying to understand some nuances of the pagination. Specifically, what is the difference between fetching the "current" vs "last" pages?
