Right to the point...
Subtasks of tasks
Have a task comprise of other subtasks in a similar UI to this bulleted list I'm currently typing
Completing all subtasks can then mark the parent task as complete
Example could be... A user keeping track of chores for the day
The parent task would be "Complete Chores"
The subtasks would be "laundry", "vacuum", "grocery shopping", etc.
The user would check off each subtask as they were completed
Once all of the subtasks are marked as completed, the parent task is also marked as completed
Ability to reference the instances of tasks between notes
If I create a task with subtasks. I could then reference any task, parent task, or subtask (individually or in groups) in other notes
Example could be... A student creating a study guide
Parent task of "Read Chapters 1 - 3"
Subtasks on that parent task for "Read chapter 1", "Read chapter 2", and "Read chapter 3"
Then they can create a new note for each chapter, reference the corresponding subtask in each note, annotate their notes for the chapter, and mark each subtask as complete as they go along to track what they've studied
I love the new tasks feature, it may very well convert me from a free user to a subscribed user once the early access is over, but with how I'm currently using Evernote, this subtask feature combined with the ability to reference specific instances of tasks/subtasks would be an absolute game changer.
Feel free to reach out in any way about this. Thank you!
