I am wondering how a "design your own home" is going to work. I know what I want: lots and lots of weapon plaques, mannequins, and shield plaques. Having a "trophy room" with various things I've killed doesn't interest me. So will I actually be able to fill each room with weapon plaques, or will I just have the choice of adding a trophy room or not? Adding a garden or not? How much control am I going to have over what things go in a room, how many, and where?
As for the crafting angle, it seems that the add-on will have what I want: smelter, forge, workbench, grinding stone, enchanting table, alchemy lab all in one place. Right now Breezehome comes closest with Warmaiden's next door. All it lacks is an enchanting table. So this new add-on will certainly fill that need.
