Sampling tool for transform, rotation, scale and size

Hi, would be nice imo to have this tool. How I see it in action: When one (or more?) objects are selected, user can lock on sampling tool to copy values from any other object, just by clicking it in the viewport or outliner. In example on the picture user is about to copy Y transform value from big cube to the small one. This will move small cube to the center. If XYZ size would be lock on - it would resize the small cube to match the big one also.
