Add more to the villages

Everytime I see a village, its just a few animals, houses and farms. But I never see any villagers or iron golems. It would be more fun, if you could interact with the villagers and iron golems. Also could you add more mobs like for the desert, in the villages you could add a camel or donkey. You could also add for the normal villages, horses and maybe wolves or dogs then we could have a pet dog or smth.
