Double Ender Chest Plugin

DoubleEnderChest expands the ender chest from 27 to 54 slots without risking items already stored in the vanilla chest.

The first 27 slots use the real player ender chest inventory. The extra 27 are stored separately by the plugin. Existing ender chest items are never overwritten on install — vanilla data is only read and written when a player opens the double chest.

How players use it The main way to open it is right-clicking an ender chest block, with vanilla lid animation and sound. Optional commands like /dec and /doubleec can also open the GUI and are fully configurable in config.yml. Vanilla /ec and /enderchest are left alone.
