Looking at conflicts with parents, I often find that the timeline will show very early born children of the mother or father. (Eg under 10 years old.) This is often due to bad merges where the spouse might be less than 10 when giving birth.
Is it possible to get better overview before merging so that novice users does not make this mistake that ends up with impossible timelines? Then maybe the undo merge function does not need to be made for non-pro users, and the curators will have less un-merge job to do. Thanks!
