I love the personal list addition in 3.0, as I've had a similar setup previously called my "catch-all" list, which was private to me and I added all parent tasks I was associated with (our org. assigns subtasks and leaves parents unassigned for reporting purposes). I would love to see the ability to add the personal list to a dashboard or otherwise as a filter, when using the "location/list" criteria. This would help be able to see time tracked and progress from the higher level of tasks, and be able to create multiple views using the single list, where the 3.0 home card can only be setup and used one time.
