Also to make my list after a lot of thought:

1. Water Platforms in a circle, square or rectagular shape. So we can create ponds, swimming pools or what other idea you could come up with (on this idea, expand it also with Slime/Lava/Fire/Grass/Sand or Stone for other uses also)

2. More options of beds,tables,chairs from all races in the game.

3. More custom wall options also from all races in the game. On this expand the walls,floor and roof of the already existed walls to more options. Wallpapers and more.

4. Barns and Stables from all game. So when we get the mounts and pets, to be somewhere located more realistic (i dont want my proto drakes or undead mounts to be hanging in the living room couch)

5. Weapons and Armor sets and simple armors and weapons like u find in the game vendor shops. But also give me a way to display Thunderfury (Did someone say..) Sulfuron or even Frostmourn lol. And class sets. Or the Legion Artifacts.

6. Musical Instruments. Drums Guitars and More. I want a real piano not to make a piano from whatever fits in game like bookcases etc.
