Ability to move containers with items in it cant open but carry around in arms till get it where you want it.
Now if you could add a system in game in future so when you go to lay something down a red circle shows up on ground letting you know as you move mouse around where the circle is is where the object gets laid.
You can pick up contianers with items in them and carry them on your back as long as you have no other backpack on you and have the strength to carry whats inside the container.
When you drop a container or any other thing it apperas directly in front of you so I don't think there's need for "the red circle".
