I wouldn't really call it a reset button in this case. It's not like they are erasing the destruction of the Enterprise, more like getting a chance to refit the Galaxy Class but keep the basic model design.Reset button: letting you have your cake and eat it too since "Cause and Effect."
No, I meant that they should have just crashed/destroyed the ship and had their effectsapalooza, and at the end hit a reset button and undid it.
