Actually QuickStack 1.2.0 — Individual Container Transfers

New: Individual Container Transfers

Added two compact arrow buttons to supported container and backpack interfaces, allowing items to be transferred directly between your inventory and the currently open storage.

• ↑ Up Arrow: Transfer items from your inventory into the open container or backpack.
• ↓ Down Arrow: Transfer items from the open container or backpack into your inventory.
• Normal Click: Transfer only items matching those already present in the destination.
• Shift + Click: Transfer all eligible items, including equipment, until the destination is full.
• Both arrows are vertically stacked, with compact tooltips explaining their functions.
• Supports vanilla chests, barrels, shulker boxes and Inmis backpacks.

Inventory Protection

• The player's hotbar is always excluded from arrow transfers, regardless of other configuration settings.
• Gold and red locked slots cannot have items transferred into or out of them.
• Item NBT, enchantments, stack limits and inventory insertion restrictions are respected.
• Prevents accidental backpack nesting when transferring items into an open backpack.
• Transfers only interact with the currently open container, without affecting nearby storage.

Configuration & Compatibility

• Added options to enable or disable individual container transfers.
• Added configurable arrow visibility and positioning.
• All new settings are accessible through Mod Menu or the configuration files.
• Improved server-side validation of inventory transfer requests.
• Existing configurations and saved slot locks are preserved when updating.
