One feature I’ve found extremely useful when organizing work is the ability to see down into a hierarchy of child items. Here is an example from Wrike:
You can see in the table view an item with children has an “>” indicator to show show you those items are there. But it is collapsed in this view, so you don’t see them.
Then, when you click that, it opens up the sub items so you can view them in the context of the table, too:
I think this would be a great addition to the table view!
