I hate to say it but new notification setting change does not help solve the problem it was meant to do. Yes, now you can toggle on/off certain notifications but you have to do it by groups of messages. There are important kind of messages and ones that are not so much relevant within every group and you have to toggle them all or none. You can disable pop-ups for all diplomatic messages but not for specific types. For instance, I may not want to see 'New Grievance Available' pop-ups, however, war declaration between AI empires or news about downgrading treaties are important ones that I still would like to see. 'You successfully ransacked' messages are rarely important to be reminded, whereas, I want to be alarmed immediately when I'm the one being ransacked. Unfortunately, the new notification system is still like accept it all or nothing. I immediately ended up disabling all of them and will keep manually checking important one as I used to do before changes.
