Can you restrict access [to stop saboteurs on your ship]?

You'll be able to restrict access. So with the security panel, you'll be able to say, I'm locking all the doors. Some joker's on board my ship doing something, so I'm going to lock all the doors. Then I, as the captain, will just unlock them one by one and go, nope, nobody in here. That's restricted to the main doors in the ship, not the individual hatches on it.
