EnchantHider

Depends on ProtocolLib. If you do not have it, download it here.

This plugin is fairly simple. Without this plugin, when you hover over one of the enchants in the enchanting table, you can see a preview of what enchantment you're going to get.

With this plugin, the preview will be removed, as it was in 1.7.

In the configuration file, you will find one option named bypass-permission. By default it is set to none. If you change this to something else, i.e enchanthider.bypass, then players with that permission will be able to preview their enchants, and those without that permission will not.

I made this because I couldn't find anything else that did something similar to the plugin, and there was also a Spigot forum thread relating to this.
