It would be fantastic to have hierarchal grouping options. For example - I would like to have the ability to group by Workflow then by Status. Within a space or folder, we may have different types of work that live within different workflows but currently, the best grouping option is by Status, unfortunately that can look quite messy and then requires a number of different tables with different filters to navigate through. Ideally, we'd be able to group by a field or data point and then break that down further into sub-groupings.
