We would like to have the ability to apply custom sorting/grouping to
the new Home area. In My Work, we were able to do this by adding a
custom field to My Work in the layout template (for example, "task
owner") and in so doing, would have the ability to sort/group by that
field in My Work. We specifically want the ability to sort by task
owner, but I think this idea should apply to custom sorting/grouping in
general.
