There are two things that I would like to be able to limit regarding adding/removing items to a sprint.
1) If the Sprint is active (is started) I would like a confirmation dialog to appear before adding/removing the items. The reason for this is when planning the next sprint it is easy to acccidently drag items into the active sprint rather than the next one. These then have to be removed but show up as scope change
2) I would like to restrict who can add/remove items to/from a sprint to ensure that only the "Product Owner can do so and not members of the dev team.
