Steal from Villagers
Why trade when you can steal? Sneak up on villagers, reach into their pockets and grab whatever you can. But be careful, the village is watching.
How it works:
Get behind a villager with an empty hand, sneak and right-click. You'll see what's in his 3 pockets. Pick an item and a needle starts moving across a bar. Press at the right moment, when it's inside the green zone. Miss and you're caught.

Every profession carries different loot:
Armorers carry chainmail and diamond armor, toolsmiths carry pickaxes and axes, farmers carry bread and carrots. The loot comes straight from the profession's trades and is different every time. The more valuable an item, the harder it is to steal: more hits, a smaller green zone, a faster needle. Pockets refill every day.

Easier at night:
Villagers pay less attention in the dark, and sleeping villagers can be emptied almost in peace. As long as you're sneaking, they won't turn around to look at you either.
Caught!
The first time, you get a loud Hmm and the whole village turns to stare at you. The second time, every villager nearby raises their prices for you. From the third time on, the villager kicks you backwards like a donkey. So better not pick a villager standing near a cliff. A few days without getting caught and it's all forgotten.

Witnesses:
Nitwits have nothing in their pockets, but they see everything. If one catches you, he runs to the village bell and rings the alarm. Kids run to the adults and snitch, unless you catch them first. And if an iron golem sees you, you'd better run.
Compatible:
Trades from other mods automatically end up in the pockets too. All values like refill time, night bonus and witnesses can be changed in the config.
