UI:
the new UI looks nice but that's all it has, the usage of multiple windows sounds good but where is the point in having them when the space is not there to view the all at the same time? but its good to view an player profile or to manage the alliance while in the forum
screen: you can only completely view two windows of the four open windows at the same time on a 22 Inch screen (click picture for full size)
one more really annoying point about thew new windows (i assume to help sell the administrator) you can only open one building view at the same time (eg. senate, barracks, quarry,..) and since there are no real links tabbed browsing becomes unusable, the new tab only shows the map
also really nice is the "Go to" function since it close all windows and brings you to the town on the map, after that you have to guess which town since there is no target town marked(maybe only a bug), so checking the location of a players towns means before using a "Go to" you need to ensure that you have saved all your work(eg. send the new mail or forum post), than you can use the "Go to" and after checking the first town on the map you have to reopen the player profile, select the next town, use the "Go to" and that until you have them all, sadly opening the goto in a new tab is also here impossible even though i manged most of my attacks this way, well maybe the attack planer will resolve that.
i have not been attack yet but i assume that you only can see the attack on a town when you hover the mouse over the symbol for troop movements like this
its questionable why the most important information are only visible with an mouse hover
suggestion:
1. don't close all windows when using "GO to" maybe minimize.
2. change the links to make them usable with tabbed browsing.
3. add an option to chose the old(or similar) sidebar(attacks, trade, build and cast) of the city overview at the right side of the map.
new farming system:
the new farming system is good, while it gives you the most resources when you farm it all 5 min it gives also an good amount for those with less time, the only flaw is that you always need to check looting or demand to see the remaining time until you can farm again, but adding this to the popup info should be easy
