A free mod for Mount & Blade II: Bannerlord, by PajTajster.
The I Dont Care Campaign Log Filter is a mod that provides an option to filter out certain types of messages in your campaign log.
You can choose to filter out messages from certain characters and/or certain keywords.
This is a helpful tool to reduce the amount of useless information that is being displayed in your campaign log.
It helps you to know when your fellow vassal or ally is being demolished by your enemies, while you are not being spammed about some Khuzait lord or village being raided on the other side of the world.
It is a tool that checks what log is about, and filters it out depending on the factions involved (or different settings).
