Crawling?

[xWolfyGaming]

There should be an action in Player Action >> Movement, that's like set swimming, or crawling. this would make for a really cool form of maybe being able to make players like 1 block tall.

This would be very nice.

That isn't possible directly, you can try to display a ghost block on top of the player to achieve this if you want.
