Yes. after running an operator you can do this in the py console:
>>> bpy.context.window_manager.operators[-1]

And for the properties as a list of {key: values}.
>>> bpy.context.window_manager.operators[-1].properties.items()

For example, they could be extended to allow saving to and loading from files (i.e.: boxModelHouse.macro), jumping to a particular time or "step", setting a playback speed and show the name and parameters of the action being performed in real-time (i.e.: Extrude face (0, 0, -0.5), Scale face (0.2, 0.2, 0.2)).
