Feature request with TC

underlining issue is unreladed to your plugin, but I wanted to ask you to add a permission for players to be able to skin the Tool cupboards. I am running into the problem where when players reskin the TC it breaks a small box above the TC and despawns the loot. I want to disable the ability for players to be able to reskin their tool cupboard. Unless you can think of something to prevent the box from breaking.
They have also said when reskinning their tool cupboard it make the loot inside the TC to disappear. however I could not recreate that.
