How can I hide tasks from my task list?
There might be some tasks, like Practice and Tutorial tasks, that you want to remove from your task list. For now, this 'Hide' feature is available on iOS devices.
To hide a task from your task list, slide the task to the left until the 'Hide' bar appears, then click on the 'Hide' bar.
To make a task reappear, go to the bottom of your task list and click the "Hidden Task" bar. You'll see everything that you hid. Slide the task to the left and click 'Show.'
