I really missing some things that i´d like to see either as craftable furniture or , well yes you can put some of that in the list for crowns
for the guys that own a castle i think they would like to put a small
boltthrower (aka ballista) on their walls, and a
round targeting practice for bow in the yard. Some fighters guild areas have these.
Weapons and Armor racks would be nice too, and the occasional
decorative Shield, Axe, Greatsword as well.
Then there is also the dire need of
hay, strewn and in a pile for the stable area.
For the lovers of undercroft design, i recommend
spiderwebs, pile of rubble, pile of dust, oh and a
tapestry - torn not to forget
Household animals, like
chicken, pig, rat, goat, but thats maybe a thing for additional npc´s that can be placed in the housing area.
feel free to add your ideas
have a nice day
