I would like to suggest the ability to automate for status columns.
Two use case scenarios, but I am sure there are other roadblock scenarios:
When mirrored status column changes to [insert status name], move item to group B.
Boards A, B & C are connected.
On board B, when a mirrored column S changes status to X, create a new item in board C and connect mirrored column S with all 3 boards.
