In the relationships tab, the cross-referenced items are listed under the column: Item, Current State, Type of Relationship, and Description. It would be nice to identify which workspaces the items are originated since the items might be cross-referenced from multiple workspaces.
e.g. certain item in [WS]Products might be related to items from [WS]Tests and [WS]Calculations. It would be nice to identify the items are either from [WS]Tests or [WS]Calcuations by adding another column called Workspace or Category.
