Although I don't have a screenshot to post (haven't gotten my copy of the release yet), I want to expand on some things that have been said. Apologies to those I repeat without acknowledgement.
One thing (of the many) that was attempted in this expansion was to give more information "at a glance", that is - on the main screen.
As you can see from Chieftess' post above, captured Workers (who are not as effecient as yours) have a different graphic. You can now tell a captured worker without right-clicking.
The sword icon indicates that there is a barracks in the city. This saves a lot of clicking when trying to locate the nearest barracks. However, unlike Harbors, you cannot see other civs' barracks, just yours.
In scenarios with locked alliances, score is kept for the Alliance, not for individual civs. But the score breakdown is for your particular civ so you can assess your own performance.
