We need the ability to change the dates on the scrum board. As a marketing agency, we have due dates throughout our cycle, rather than delivering everything at the end of the cycle. This would eliminate a lot of headaches, and allow us to work in cycles.
I'm in the same boat. In fact, I'd say the date issue is one of the biggest factors in moving to Agile Marketing Management. Tasks have due dates that are dictated by things entirely outside of the iteration time boxing, like editorial calendars, print dates, and intersections with product launches and other promotions. Forcing all the tasks/issues to have the same end date as the iteration screws all of this up.
