In the table view, under Subitems, the option to "Show in Table: Single list of tasks" is extremely powerful, especially when you are working to do mass changes to workflows or updates of some kind. That view has allowed us to make some mass edits very quickly and easily. However, sub-items of a task are not shown, they simply do not appear in this view.
This seems crazy: The entire point of this view is that folder structure and project structure is removed and you see the tasks in a flat way. This is brilliant and works uniformly EXCEPT it does NOT support sub-tasks. In that view, sub tasks are _not shown at all_. As a result, doing mass updates such as mass change of item types, workflow corrections, or other cleanup require you to painstakingly search for sub-items.
The hierarchy of Wrike including folders, sub-folders, and sub-items is one major strength of Wrike, so this limitation seems really unfortunate.
