TrapUpgradeEnder - Improved Ender Chest Upgrade

• Dual economy - The plugin supports both the regular economy through the Vault and the alternative currency PlayerPoints. Players can choose whether to buy slots with money or PlayerPoints.

• Flexible purchase system - Players can buy slots individually with a regular click, or in rows with a Shift+click at a significant discount. The system automatically calculates progressive prices, with higher prices for further slots.

• VIP system - 4 levels of privileges (VIP, Premium, Legend + basic) give players more basic slots and personal discounts up to 50%. The system is integrated with any group plugins via Bukkit Permissions.
• Queue system - Unique protection against cheating: players cannot skip slots and buy them in random order. They can only buy the next available slot in the queue.

• InvSee system - Administrators can view and edit players' ender chests in real-time. Changes are synchronized between the admin and the player

The plugin has a very flexible and simple configuration, which gives it an advantage over other alternative plugins.
