Something Id also like to see regarding pickpocketing is for NPCs to not always have psychic knoowledge of having been pickpocketed no matter how small a thing. Like if you overshoot the difficulty by a certain number they wouldnt even notice anything missing. It is a bit immersion breaking when a guard immediately notices a missing key, or something really small. The point of sleight of hand is to be able to take something without its owner noticing right?
