Nobody has something to hide in their inventories, right? For less inventory-privacy: Transparent Inventories! Simply ALT + LEFT-CLICK (default, can be configured) on any other player to open his inventory - without admin permissions. Boost productivity by sharing resources the easy way!
Providing the player with new tools or adjusting the game interface, without fundamentally changing gameplay.
