I've stacked up the tile and growth ones by opening NotificationPanel.lua and adding a "B" to NOTIFICATION_CITY_GROWTH and NOTIFICATION_CITY_TILE.
The city tile growth should be condensed by default in the EUI version, IMO. There's no worthwhile info there, and adds a lot of clutter. I agree that the growth one is a bit of a mix, less clutter but harder to see the info. Though by mid game you already know where most of them are coming from.
The one telling "Your city is now X pop!" one could go away, or at least, an option to remove it.
BTW, Gazebo, what is the "yield conversion" one? It's one I don't know exactly where it's coming from...
Thanks for your hard work, the game is extremely awesome now thanks to you!
