Subtasks are one of the most useful parts of Asana. They let you break a big task into smaller steps, assign pieces of work to different people, and track progress without losing sight of the bigger picture. But working with subtasks used to take a few extra steps. You'd leave your project view, open a task pane, and work from there. If you wanted to turn an existing task into a subtask, you had to open a menu, search for the parent task by name, and click through a few more steps to confirm.
