View for filling a milestone/sprint
To make it easier to see whether you're over or under-scheduling, we should make it easier to fill a milestone.
Right now, the issue boards 'add issues' screen is a great example of a view like this, but it lacks the ability to add things to a milestone (i.e. it's used to add things to the issue board) and it doesn't give you the required metadata.
You should be able to do the same for milestones, but you should be able to see:
- current total weight
- current total nr of issues
- weight of each issue/epic you consider to add
To also consider:
- set a max weight for the milestone
