Some artist will like the in game texture preview with no need to buy the texture items to preview their art or going to Toribash Texture.com. Something like the items preview feature but without dismembering the tori will be aprecciated

You still can put the .tga files named in a correct order to the customs folder, then use the /lp [0/1] [name] command ingame to see the textures.

Although a simplified and somewhat "official" way for this would be a great addition!
