It was created to bring multiple small addon-style tools into one location, and it will continue to be updated and expanded as World of Warcraft changes through future expansions and game updates.\n\n- |cffd8a84aGear Scanner:|r Automatically equips gear upgrades as you loot them based on your spec's stat priorities, with optional loot-roll, soulbind confirmation, tooltip, locked-slot, and Pawn support. Inspired by AutoGear, with ClassCodex used for stat priority data.\n\n- |cffd8a84aUI Tweaks:|r Filters annoying red error text from your screen and lets multiple Blizzard panels stay open together. No Auto Close behavior was inspired by NoAutoClose.\n\n- |cffd8a84aCVars:|r Browse live client CVars, compare current values against Blizzard defaults, edit selected values, and filter to modified-only settings. Inspired by AdvancedInterfaceOptions. Modified CVars appear |cff55ff55green|r in the list.\n\n- |cffd8a84aAutomation:|r Speeds up interactions by auto-selecting gossip options and automates Auto Unshift for Druids in combat. This can be helpful if you use GSE, also known as Gnome Sequencer. While enabled, it also hides the shapeshift-form error from your screen; turning it off restores Blizzard's default error display. Auto Unshift for Druids was inspired by EA Auto Unshift.\n\n- |cffd8a84aProfessions & Lookups:|r Adds a secure hotkey overlay to profession items in your bags and creates copyable Wowhead links from supported tooltips. Profession item behavior was inspired by Molinari, and tooltip link behavior was inspired by Wowhead Quick Link.\n\n- |cffd8a84aProfile Vault:|r Saves and restores action bars, macros, and keybind backups. Inspired by MySlot-style profile backups.\n\n- |cffd8a84aExport Strings:|r Save, manage, and retrieve text strings like UI layouts, WeakAuras, or talent builds. This section was created for Sin's Toolkit.\n\n|cffd8a84aAvailable Commands:|r\n- |cff3498db/stk status|r - Prints the active status of your toolkit features to chat.\n- |cff3498db/stk scan|r - Forces a manual gear scan for upgrades.\n- |cff3498db/sau status|r - Checks the status of Auto Unshift for Druids.",
