I think it would be neat if villagers could give you quest. This can even be made compatible with different mods. I feel that it would make villages much more immersive. Maybe if they have a diamond over their head that means they have a quest, and maybe there can be some sort of quest log where if you visit multiple villages the quest log can keep you organized. Then when you are done with the quest you can return to the villager or use the quest log to teleport to the villager who gave you the quest.

Would be so great an enhance mob interactions by recording personalized profiles, enabling contextual understanding for player commands (e.g., attack, marry), and introducing dynamic conversations. This would allow mobs to suggest missions, accompany players, and respond more comprehensively to in-game dialogue.
