This release is a large shop/GUI + configuration update, plus expanded physical currency customization and a safer config updater.

Added

• SmartSpawner + Vault economy provider compatibility (SmartSpawner can use RelishEconomy as the economy)
• Shop favorites system:
  • favorites.yml storage
  • Favorites button in shop GUI and a dedicated Favorites category view
  • Favorite state messages: shop.favorites.added, shop.favorites.removed
  • Favorite items can render with a glow effect in the shop list
• New purchase flow GUI (Premium):
  • Clicking an item opens a buy GUI where players can increase/decrease quantity
  • Confirm purchase, cancel/back returns to the same category page
  • Favorite toggle from the purchase GUI
  • Confirm button can show player balance in its lore (configurable in gui.yml)
• show-unpriced-items option for shop browsing:
  • When enabled, items without a configured buy price can be shown as disabled instead of hidden
• Physical currency enhancements (per currency):
  • Optional crafting recipe support
  • Custom model data support for currency items
  • More customization options for physical currency item templates (material, name, lore, visual flags)
• Improved config restoration/merging (config updater):
  • Automatically restores missing bundled files: config.yml, shop.yml, prices.yml, gui.yml, lang/en.yml, lang/ar.yml, lang/pt.yml
  • Merges missing keys into existing YAML without wiping server edits
  • Automatic backups: <file>-backup-YYYYMMDD-HHMMSS.ext

Changed

• Shop layout and defaults were reworked to match Creative inventory categories more closely (order, grouping, and paging).
• Operator/utility category is disabled by default in the bundled shop configuration.
• GUI sorting markers are configurable (set active/inactive symbols in gui.yml).
• /re reload now reloads GUI config, shop categories, and purchase flow state more reliably.
• Placeholder formatting adjustments:
  • Compact/plain formatted placeholders no longer force currency symbols when using the plain variants (use the symbol-specific placeholder for symbols).

Fixed

• Many "invalid shop item key/material" warnings by hardening material/key parsing and validation for modern Minecraft versions.
• Premium command registration and tab-completion reliability after /re reload when license state is active.
• PlaceholderAPI rank placeholders no longer degrade to N/A after server uptime (baltop cache refresh + safer fallbacks).

Documentation

• Updated plugin documentation pages to match the current 1.0.9 shop/GUI and currency features.
• Updated the repository README.md and docs site pages, and added/embedded screenshots from docs/assets/.
