The Sprint Health Gadget is quite useful for our team, but we have a very simple workflow (Open-->Done-->Closed - with some blocking options along the way). Right now, the gadget only shows us what's complete when it's signed off as closed. Is there a transition or a trigger that it uses to determine the green bar?
We like having a distinction between the assignee being "done", and the Project Owner marking it as "closed", but not seeing the status of the sprint until everything is evaluated is not so useful.
