Not interested! - A Polite Way to Dismiss the Wandering Trader
This mod solves a small but annoying problem in Minecraft - persistent wandering traders. Now a special button appears in the trade interface, allowing you to politely ask the trader to leave.
The developer came up with this idea after one such trader settled exactly where a vineyard was planned. Instead of radical solutions, it was decided to create a civilized way to get rid of the uninvited guest.
In multiplayer mode, the trader may go to another player if they are nearby but not too close. If there's no one around, he'll simply continue on his way.

A simple but elegant way to get rid of a trader who interferes with your building plans or simply annoys you with their offers.
