not sure if anyone has ever suggested this or not, but what about being able to grind up all those extra clutter skulls for bone meal?

i know i always end up with a dozen of so in my inventory on accident every time i sweep a house or alchemy shop

That would be interesting... But I think there's plenty to be had already from skeletons and the like.

Now, melting armor and weapons back down into ingots, that could be something.
