Aha! has almost zero Kanban functionality, adding a way to group feautures on the workflow by anything else than just assigned person such as some custom fields would enable classes of service to be added simply and quickly and make that board much more useful.
Thank you for the additional detail! I am going to merge this with another related idea.
Thanks for reaching out! Could you add some more information about your use case and where you would benefit from a 'group by' option?
