There are some minor issues, like one or two new houses, a new gateway (which look very cool) and some miscelaneous that I missed (like many ships, a stonemill, a better looking well... you know, minor issues that contribute to give life to the scenarios).
By the way, I've been thinking that we need to give more life and personality to the interiors by adding things very appropriate with the timeline: mural paintings, tapestries and mosaiques. Mural paintings fit better in the Mediterranean world, while tapestries, even though they were everywhere, would look better in Northern and Central European environments, and mosaiques are definitely an Italian and Byzantine issue.
The paitings would occupy most of the wall. Have you seen Kingdom of Heaven? In the room inside the castle of Ibelin has some skeletons painted on the walls, saying "Quod sumus, hoc eritis" (What we are now, you will be), very gloomy but deeply inside Medieval thought and, besides, accurate. KoH maybe a bad film, but its ambientation and atmosphere is really well-done.
