It is definitely not on the chopping block, as it does deliver on some of the design goals we set out to achieve with it.
What does it do that the notification flags did not do better, more easily, and more efficiently? The notification flags, especially once you've gotten used to them, tell you what is going on at just a glance. When I am playing EU4 and I see a red flag pop up, something is bad, and when I see that infamous crossed pitchfork and flag, I know I am about to have a rebellion. When it is yellow, there is just unrest. There are so many other icons that I know at a glance, without even needing to page over them, and they take up a tiny amount of the screen while conveying a lot of information very efficiently. What I don't see is a number that is glowing where I need to click on it (usually pausing while I do this ordeal, since it can take a while sometimes and also covers the middle of my screen), sometimes need to scroll up and down to find the notification, sometimes needing to open up a folding menu of more notifications, and then page over the notification to clear it. Sometimes it is useful, but oftentimes it isn't. Why do I care that by level 30 trade route is unproductive? It will downsize slightly and become productive again pretty quickly. Or if a trade good is bouncing between causing a shortage or not, causing a new notification every week of game time that I need to go and check. There are so many notifications for things I don't need to know or care about, hidden between things I really do care about. I have to check, to make sure the notification is pointless and not important, but I certainly can't just leave it open because it takes up the middle of the darned screen. Absurdly inconvenient.
What are the advantages of this system, over say the classic notification system of EU4, CK2, Stellaris, etc.?
