Description:

This mod adds a portable Package item with a 4-slot internal inventory saved to the item, plus a Courier Postbox interface for sending items to online players. Right-click a Package to open its UI, place items into the slots, use shift-click to quickly transfer items between your inventory and the Package, then close the UI to save its contents; while a Package UI is open that specific Package is locked in your inventory so it cannot be moved or altered, and Packages can be placed inside other Packages. Open the Postbox to choose a recipient from a cleaned-up dropdown of currently online players (long names are truncated with hover tooltips), select a recipient and click Send or press Enter to deliver items — Send is disabled when no players are online and the dropdown updates cleanly without stacking or visual artifacts.
