As a ScrumMaster, in the DependencyBoard, with "Column By" iteration and "View" Backlog items, I need to be able updating the backlog items iteration directly with drag-and-drop in order to avoid opening eahc backlog items I need to update.
Indeed, my team is providing services to several teams in my company. Our stories are often required before other teams can finish their developments.
I use this dependency board to roughly plan my team activities even though our process is Kanban.
It helps me synchronizing with these other teams by visualizing timeline and dependencies.
I often display this board while discussing with other teams and I would really save time and increase visual management by being able update itearation directly from the dependency board.

Thank you
