It's an interesting idea and certainly sounds good on paper! I think there may be some tricky questions with that, though, as there is no way even with an automated system to view every collision. In many simulations, there are lots of collisions happening at the same time, for example.
But we have discussed ways to make it easier to watch the interesting things that are happening in a simulation, or at least to be made aware of them. These tools aren't currently high on our priority list, though.
