as a sugggestion could u add group perms for individual items?
Different group perms for items (VIP ect.)Suggestion
im not 100% sure it would be possible given the dictionary style im using but il look into it, but for now if you don't want an item in the list you'll have to remove it from the json file manually. you can also add any item to the list you want as well long as you can find the itemid, skinid and/or prefab name

i know this isn't perms but you can also enable and disable specific items by changing a setting in the craft settings, i updated the configuration example to show where that setting is located.
