HUSBANDRY:
I'd love to see more to do in the animal husbandry area, similar to the level of detail that has gone into crafting;
Being able to change the hay in the hen box, and use the old hay as compost/fertilizer
Better quality or quantity animal produce with better quality food
Bedding or shelter areas for animals playing a role in satisfaction / breeding
Ability to brand some animals (could include paint brands for animals like sheep/goats)
Faster growth rate or greater yield for crops/berry bushes/fruit trees when a beehive or skep is nearby
Fish farming
HUNTING:
Special items/activities for hunting might be fun, such as
creating hides
gillie suits
animal call whistles
blood trails or tracks for animals that have been tagged and are running away
More traps / trap types e.g. for larger game
If wolves were ever to be able to be domesticated, training them to help with hunting would be great, like flushing out game, retrieving killed small game, or helping track down animals (whether it's just any animal, or a specific kind of animal, or a specific animal that you've already tagged with an arrow/spear etc).
Unnecessary requests/comments:
Obviously I would love (in the vanilla game) be able to tame wolves or purchase tame wolf pups from traders (and pat them / play fetch / guard animals and crops), sell captured wild wolf pups to traders, tame mounts (riding a bighorn sheep would be absolutely sick) - having a sled or something that could be pulled by animals would also be fun I think... but I assume all these items have been previously requested and don't need to be stated hahaha.
