The ones on the right-hand side of the screen in EUI. I always check them to make sure I catch things like when cities grow so I can pick the next tile, when there are new city state quests, etc. But it would be really nice to be able to turn off some of them - for example, I don't think I have ever cared to hear that one of the AIs has pledged to protect a city state. I'm more than happy to dig in the files/code to do it, but I wouldn't know where to look. Can anyone point me in the right direction?
