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.

To be clear, are you saying you'd be happy to click on every single NOTAM to "mark as read"? That's what such a feature would entail, as we certainly couldn't assume that just because the NOTAM had been shown in your briefing that meant it had been read.

Yes, indeed clicking each one would work. If there’s a better way then go for it.

Surely, most users when viewing will click on a Notam to highlight its location on the map. This itself could initiate the ‘mark as read’ change to the Notam status.

Just look at all the Notams for cranes or UAS over London, there’s so many of them it’s hard to know which are new unless you have either a good memory or are using some sort of tracking system - highlighting would focus the user to new Notams, enabling better situational awareness and less time spent trawling through the same Notams over and over.

We are part way there with the ability to hide a Notam but this isn’t possible for all Notams.

This is win-win for flight safety.
