Picking up Blocks

This would be like the feature in the recent April fools snapshot. Ik it was a joke but I feel like this could actually be a great addition to the game. The player could do this by crouching and then clicking the use button (with an empty hand). This would be especially helpful with chests, instead of having to take all the stuff from inside the chest, you could just pick up the chest and move it somewhere else. This would take up one slot of your inventory. While this is happening however, it will prohibit the player from using anything else in their hot bar/ inventory until they place it back down. And it could possibly also give the player a slight slowness effect.
