Enabling Notification Quick-Add
4.Do lets you quickly add a task straight from your notification shade — so you can capture ideas while using other apps without breaking your flow. To enable it:
Tap the overflow button.
Tap Settings.
Tap Notifications.
Tap the Notification Quick-Add switch to enable it.
Note: This adds a simple task to your default quadrant. You won't be able to set a due date, tags, subtasks, or other task details through this method — open 4.Do directly to add those.
