As the field "Backlog Priority" in stories is a text input and not a dropdown, it would make much more sense for the Backlog Priority filter option to be a text input field rather than the current dropdown offering "Must," "Should," "Could," and "Won't." My team prefers to rank priority using number scales or "High," "Medium," and "Low;" modifying this filter would allow them to get much more use out of this Priority field. This would be useful to any teams using priority scales that are not "Must," "Should," "Could," and "Won't."
