Technically, you already can moonwalk.
Just set your running type to Relative Mode, use left Alt to freeze your head, and walk backwards.
You can also use D and A to spin around while using Relative Mode.
Just pointing that out.
I agree with all those new actions, though. They'd be awesome to see in the FH animation.
What I don't agree on is the new charrie models.
FH is based of off IT, like xRuby1234x said. IT only had a lion model. Plus, FH is an animal game, so having a human model would kinda throw off and ruin the whole course of the game. People want to escape the human reality and become their inner animal, not have another human problem to face.
Just my opinions.
