What is the enhancement in mind? How should it look and feel?

Please provide any additional information below.

I have a suggestion. prevent players from changing other players spawners or breaking other player's spawners. You could set up Permission EX with a node that is something like player.changeothermobspawner.no or soemthing like this and if say I have that node in the member section, then it will block members and guests from changing other people's mob spawner. This would be useful on a server to prevent griefing or people changing other people's set spawners to something else when they shouldn't be.
