Strict Double Jump Detection: The mod activates only when you press the jump key a second time while in mid-air (Double Jump). The logic has been refined to prevent accidental activations when jumping from the ground.
Smart Elytra Swap: Upon detecting a double jump, the mod automatically searches for an Elytra in your hotbar (slots 1-9) and equips it instantly.
Automatic Landing Detection: When you touch the ground, the mod detects the transition and automatically re-equips the best chestplate available in your hotbar.
Intelligent Chestplate Prioritization: Includes a smart scoring system that prioritizes materials (Netherite > Diamond > Iron...), durability, and enchantments to ensure you always equip the strongest available protection.
Full Visibility (No Silent Swap): Unlike other utility mods, this one performs a visible swap: Physically changes the hotbar slot. Triggers a hand swing animation (swingHand). Holds the item in hand before restoring the original slot, ensuring both you and others on a server see the equipment change.
Total Control: Includes a toggle key (Default: K) to quickly enable or disable the mod, with notifications.
