Llama change ideas

I don't like how you are able to ride llamas but not be able to control them with carrot on stick, they should be able to be ridden, since they spawn in mountainous biomes, I think they should have a climbing ability like spiders but have it determined by the strength variable, and since they could be controlled with carrot on a stick if you left click in a direction your llama or all the llamas in a group could spit at that direction, that would definitely make llamas more useful.
