Integration between Tasks and other features (Notes, Habits, etc.)
Ability to link a Task entry to another Toodledo feature (Notes, Outlines, Lists, Habits). This would improve integration between the different features.
Create a Task that refers to a specific Note with more information needed to complete task.
Create a Task that will Log a Habit as done when the Task is completed.
Add Outline items to Tasks, and share completed status.
