As mentioned in my reply to v4 0/5, I am quite strongly opposed to using the
Selection API for this as opposed to using controls. Unless someone can provide
strong arguments for using the Selection API, I am inclined to reject this.

Sorry about that, I probably should have been reviewing this series sooner.

Regards,

Hans
