Would be nice if it was possible to somehow hide certain commodities (such as smuggled goods) from being displayed when scanning. Then we could possibly implement a command that would take like 5-10 seconds to output a list of cargo that the ship is really carrying. That coupled with the /nodock command would make for some nice minigame for cops and smugglers. Smugglers would actually try to hide smuggled cargo among other goods, while cops would have to think fast to decide whether to order someone to stop for scan or not - and now asking to stop for scan would actually make sense.
Of course the hardest part is coding the damn thing...
