As the title suggests, highlight any new or unread Notams in the Notams tab, would make reading them more effective and efficient as it would differentiate between those you have already read vs any new ones.

Upon reading (or maybe clicking) on a new notam, it becomes unhighlighted. And this would be reflected across multiple devices for the same user/account, so if like me I use iPhone and iPad, I wouldn’t have to see the same new Notam highlighted twice if I’ve already seen it on one device.
