As the title suggests, the ability to move containers with items in them would save up so much time. However, it could come at the cost of more exertion the fuller the container is, but dependent also on container size. So a 300lbs crate that's totally full will give you 100% exertion upon putting it down, whereas a full 25lbs container may give you half or 1/4 exertion.

Since it already works for workbenches, why should it not work for containers?
