Minehut already offers EssentialsX don't get fooled because its named just essentials if you run /essentials version on your server you will see that it is in fact EssentialsX (Not sure why they don't just change the name to EssentialsX).
They can't add leaked plugins, here is the spigot link for context (https://www.spigotmc.org/resources/️-advancedenchantments--create-custom-enchantments--173-enchants-.43058/)
A fork of this plugin would be really useful especially for editing messages from plugins that don't have a config or we don't have access to the config because it's not .yml.
Not exactly sure why this plugin is not here yet, its an essential part of world guard for many servers.
