It's a common theme in the Moot to argue about who killed who, how many times, and how did those kills happen. It'd be cool to log deaths and make them publicly searchable, to allow us to see the dead character's stats, gear at the moment of death, the wounds, etc.
A similar feature is already existent in Eve online, for the same purpose, as proof of kills.
EDIT: Also pasturing!
What this would mean:
Grazing animals will now prefer to graze instead of consume trough fodder, only suffering quality reduction if they haven't been fed regularly. Basically you'd have to take grazing animals OUTSIDE, TO UNCLAIMED LAND, and keep the animals together in a herd while they eat, for example, for roughly 30-60 minutes every second day. The bigger the herd, the more difficult to keep it together, they'll stray away, requiring more people to safeguard the herd, therefore providing a soft limit to how much animals you can maintain if there's some kind of penalty to the herd animals running away, and also providing an opportunity to go outside of your palisade, and incentive to steal the herd animals by raiders. A new engaging way of handling animals.
