Nested lists Unlimited levels of lists
To use nested lists 
is a flexible way to group tasks. You can structure your lists as follows.
- A list and a task can have the same properties.
- The number of list levels is unlimited. Create a sub list by selecting “Create list” from
the task quick menu. -
SaveYourDay’s smart features for both lists and tasks are available in the quick menu . You can for example always copy or email a list , independent of level in the list hierarchy.
Tip!
It is possible to give the same start and completion dates 
on a complete list instead of putting dates on each task. This works especially well on projects and check lists.
