Arcane Backpacks — Changelog

[1.1.0] — 2025-04-26

✨ New Features

• Item Filter Upgrade — Install in an upgrade slot to control which items can enter the backpack. Configure 9 filter slots with Whitelist or Blacklist mode. Scope can be set to apply to all insertions or magnet pickups only.
• Advanced Item Filter Upgrade — Same as the Item Filter Upgrade but with 18 filter slots for more precise control.
• Compact stack counts — Backpack slots with more than 999 items now display compact labels (1k, 2k, 1M, etc.) instead of the full number. Hold Shift while hovering a slot to see the exact count.
• Backpack preview tooltip — Hover over a backpack in your inventory to preview its contents as a compact grid. Hold F3+H for a full itemised list.
• Quick transfer — Shift-click a backpack in your inventory to instantly transfer all eligible items from your inventory into it. The Item Filter is respected if one is installed.
