I want to edit Lakeview Manor because Im not perfectly happy with some of it (e.g. its to dark, not enough lighting, and the trophy room looks a bit bland). But when I open it I don't really have a chance to edit something because everything that could possibly be there is displayed. So e.g. the kitchen and the armory are on the same place and I can't see anything practically.
Is there a way to hide these things so I can make my own additions?
