MineCraft 1.21.4 (Alpha v1.1) - FastKeyBinder

Bug Fixes

Fixed Duplicate Detection Logic

Resolved an issue where the mod failed to detect and warn users about duplicate key assignments within the mod.

Resolved Config Persistence Issue

Fixed a critical bug where saved key bindings were being reset or lost upon restarting Minecraft. Settings are now correctly persisted to the JSON file.

Corrected Input Priority

Fixed an issue where vanilla Minecraft key bindings took precedence over mod macros, ensuring that custom bindings now function as intended.

Improved Combination Key Handling

Resolved a conflict where using combination keys (e.g., Shift + E) would still trigger vanilla single-key actions (e.g., opening the inventory with E). Macros now properly suppress vanilla actions when triggered.
