JEI for Horizon: versions and changes

The first playable Horizon JEI viewer, built on Horizon's native hook points (version 2).

Item Browser & Search

• Added an item panel alongside container screens, displaying every item known to the game with pagination.
• Implemented JEI's search grammar:
  • Words and "quoted phrases".
  • -exclusions and | alternatives.
  • @namespace and #tag filters.
  • $tooltip and %creative tab are not supported yet, pending access to the required data.

Recipe & Usage Viewer

• Press R to view an item's recipes and U to view its uses.
• Works over the item panel and any slot in a container screen.
• Clicking an item in the panel opens the same views.
• Added recipe pages with dedicated tabs for:
  • Crafting
  • Furnace
  • Blast Furnace
  • Smoker
  • Campfire
  • Stonecutter
  • Smithing
  • Brewing
• Supports all five of the game's recipe layouts, including cooking time and XP.
• Added a Back button to navigate through viewing history.
• Clicking a recipe slot opens that item's recipes.

Recipe Placement

• Added the + button to place recipes into the open crafting grid when the recipe book contains them.
• The button remains disabled until the recipe is available in the recipe book.
• Shift-click is not supported yet because the panel's action event does not expose modifier keys.

Item Giving

• Added item giving through Options → Mods → JEI or /jei give.
• In creative mode, left-click gives one item and right-click gives a full stack.
• In survival mode, clicking an item opens its recipes instead.

Localization & Diagnostics

• Added English and Spanish UI translations, configurable through the mod's Language setting.
• Item names are retrieved directly from the game and always respect the player's language.
• Added /jei to report the game's table sizes.
