I’ve seen this in other servers, but basically the option to fully hide your cart. For classes like Mechanic/Maestre it just looks silly and drags the look down a lot.

Personally I don’t care either way but since having a cart is pretty much mandatory for some builds/skills, it’s indeed strange the option doesn’t exist already.
