The filtering/grouping/sorting for units and buildings makes it easier to use the game in the way it is intended, but I think there are a lot of other improvements that can be made to the game UI.
In the end you want to fight civilizations and not the UI.
One thing I consider annoying is the production popup whenever the queue of a city is empty. Especially now with the new methods for production selection in the city screen. It also forces you to make the decisions at the start of the turn instead of being able to move some units first (which you might want to do, especially in a multiplayer game).
So what about instead of the popup you get icons somewhere on the screen, one for each city with empty queue. Mouseover over the icon tells you the city and what it finished constructing. If you click on the icon, it is removed and the city screen is opened.
This could also be extended so when you click on a button in the city screen, such an icon is added as a kind of city bookmark (for one time use, different icon graphic).
What do you think?
Do you have other ideas that would improve usability?
