I am currently using asana to manage development sprints. One of my project is the product backlog, while I use boards for sprints. The same task is usually in the product backlog and in a sprint.
In my product backlog I use a custom field to define the priority of each task.
A sprint is generally made up by few “must have” tasks, some “should have” ones and many “could have”. A sprint is successful if the must have are implemented in the allotted timeframe. Everything else is a bonus.
My challenge is that in the sprint board I have no way of seeing the priority of a task without opening it.
