New Lists for Jobs and Tasks lists is a Beta release.
For relevant lists, you can Group information by one or more columns, for example, Client Group, Client, Category, Job State.
Grouping is currently available in the Jobs lists, including Home - My Jobs and Client - Jobs. Only certain columns can be used for Grouping. For example, the Jobs lists can only be Grouped by Client Group, Client, Name, State, Category, Cabinet, Partner, Manager, Created By or Modified By.
