Click on a Task (recommendation: from the right end of it) and then drop it where you’d like it to be. You should see a line that indicates where the item will be dropped.

You can drag a Task along with any of its sub-tasks in one step as well.

You can also indent items (creating subtasks) by dragging the item inwards.

Best Practice Tip:

To indent tasks, click and hold and then gently move your mouse to the right until you see the indent. Then let go.
