Is NPC chatter driving you nuts? Do you feel like throwing Topper McNabb in the canals? Are you tired of listening to William and Donna fight over her doll? This chatter helps to give a city colour or "personality" but in no way affects your progress in the game. Sometimes it can fill your chat window to the point of causing you to miss important messages.
CorkIt does one simple thing, and does it well. It removes NPC chatter. the default is to only cork NPC "/says" when you are in an inn or a major city (ie. while your character is "resting"), but it can be configured to cork NPC's anywhere, including instance, and it can cork "/yells" as well.
Note: CorkIt checks if your name is mentioned and if so, does not cork it.
This is a small, efficient mod with a minimalist GUI, no libs and no dependencies.
