I skimmed several pages but didn't read every single suggestion; hopefully I'm not duplicating.
I would really, really like more rugs that are not brown or yellow. You do have some rugs in game that are not available as decorations. The Simple Merchant's Rug, which is normally peach, can be found in a green version in a house in tattooine (one of the infected citizens is standing near it), and in one or two of the Nar Shadaa heroics. I'd love to have it in the whole rainbow of colors, including White and Black, and same for the Luxurious Rug (Blue/Red style).
The nice thing about those is that they are existing assets and would only need to be recolored, and they would cover a variety of uses - merchant's for ornate design/pale, and luxurious for modern design/saturated colors. You have also done this with the Corellian/Senator's rug.
Similarly, the Senator's lounger and Voss-ka Couch would look great in Blue, Green, Black, White, Purple....
Ok, I've done that to death, so some other suggestions:
Signs that indicate the use of a room, especially ones that fit in the mini wall slots above a door. I have one house that is themed like a smuggler/bounty hunter shuttle port, and one of the rooms is an office. I'd love to be able to label it with an image of a person sitting at a desk, or if nothing else a holo "credits" symbol.... but generally the idea is to be able to label rooms, ideally with symbols, but images (photo style like the trophies) or words would be better than nothing. Office, Bedroom, Garage, Vendor/Shop, Conference Room, Temple, Cantina, etc.
And my big pie in the sky idea is to have plain colored wall hangings or flat surface so we can sort of wallpaper a room.
Thanks for listening!
PS I just wanted to add the the idea of a herd of nerfs is amazing (nerf corral centerpiece?) and I love the personnel packs and have bought every one of them. Also, anything Makeb, Manaan/Copero, and Zakuul style is awesome in my book.
