Really like the Outfits and Stickerbook thing with the equippment (though be nice to get a preview on the set items as well just like in the outfits section)
But what would be really awesome be a kind of stickerbook where all of the available furnishings could be previewed and you can see which you have and which not instead using a multitude of different tools to get a look at things bnasically wasting time and yo ucna preview in game which would have its advantages.
Also for the preview a 3D rotation is really missing so one can preview the object from all sides maybe including the controls from the housing editor.
