I would like to be able to add and track items in my device to-do list from within a page in GoodNotes. For example, possibly writing “!:Call John” would add “Call John” to a “GoodNotes” to-do list, and convert the “!:” to a check box. Completing the item in the device to-do list would check it in GoodNotes, and conversely, checking it in GoodNotes would complete it in the device to-do list.
