Naming your beer/wine would be a nice thingy, perhaps per full barrel or some such?
More mining curios: I've noticed that every so often I might find some catgold, a crystal, or a fossil, an idea would to be adding some more of these (Perhaps some only rarely droping in already rare ore types)
Ie, say, gemstones and ambers, being rather rare but a good curio (abelt perhaps taking a decent study time)
Books, perhaps made from parchment for its leaves and leather for its binding, having an option to "filp" thou papers (reading differant notes and the such) would be an intresting item
This is just me being random here, nothing overly good here :V
