Right now a task's importance level is "absolute" and an inherent value of a task/card. However, multiple teammates assigned to a card might want to prioritize differently within their own views. One person might want to make the importance level of the card "low" - because for that person, the level is low. However, another person tagged to the card might carry the brunt of the work and need to make it high priority.
It would be great to have a way to show the card's importance level as a different based on the user logged in.
