The "J" right needs to be added to the kingdom system. "J" stands for the Jail rights. I think it will be instrumental for the 5 kingdoms to police their citizens and also intruders who are causing problems which are not in Kingdom mode. Non-Kingdom Mode intruders can only be jailed for a short time, afterwhich they are deported automatically. Kingdom members can be jailed longer. If a non-KM intruder returns to the island and causes still more problems, then they can be jailed longer, or some other punishment can be done.
The police station or whatever you want to call it, on Main Island, in which people with the "J" right could go representing their respective kingdom, and put prices on the heads of individuals who have made an offense against their homeland. Wanted signs, etc.
Both of those ideas were already suggested to Stefan, and he had planned on doing both, but I havent seen either of them happen yet. So thats more or less a reminder, heh.
Also, I think things should be added so we can get exp for skills in the Agility and Personality sub-levels. Thats sorta off-topic but that needs to be done as well.
