Sacralium Improver

Chrome extension (MV3) for sorting inventory items by set and name on sacralium.game.

Features

Auto-sorts Things and Skills item grids when opened
Sort order: set group → item name → level → rarity
Direction toggle (asc/desc) applies to level and rarity
Set filter: dropdown in Things sortbar to show only items from a specific set
Tier filter: dropdown in Things sortbar to show only items of a specific level (I–X)
Quality filter: dropdown in Things sortbar to show only items of a specific rarity (Обычный/Редкий/Уникальный/Легендарный/Эпический)
Reset button: appears in Things sortbar when any filter is active, resets all filters on click
Filters apply simultaneously (AND): show items matching all selected set, tier, and quality
Intercepts game API (dictionary/get_current) to get item names and set data
No build step — vanilla JS, load unpacked at chrome://extensions
