Creative Addon Ideas for Midnight 12.0¶

Midnight closed some doors and opened many more. COMBAT_LOG_EVENT_UNFILTERED is gone. Raw combat numbers are locked behind Secret Values. Addons that replaced Blizzard's secure frames wholesale no longer work. For a moment, the addon community held its breath.

Then the new APIs arrived — 437 of them. Entire namespaces that never existed before: C_Housing for player housing, C_EncounterEvents for boss ability timelines, C_HousingPhotoSharing for social screenshot galleries, C_DamageMeter for Blizzard's own combat metrics. The Duration and ColorCurve objects give addons new ways to display time and health without ever touching a raw number. Frame:RegisterEventCallback() simplifies event handling. The Cooldown Manager is now a first-class system addons can hook into.

The "BetterX" pattern — enhance Blizzard's UI rather than replace it — is the dominant design philosophy for Midnight. Addons that skin, extend, overlay, and augment Blizzard's frames thrive. Addons that rip them out and start over break. This isn't a limitation; it's a design constraint that produces better, more resilient addons.

Every idea below is buildable today. Each includes the WoW 12.0 APIs involved, a difficulty rating, the recommended development mode, and a /wow-create command to scaffold it instantly. Whether you're writing your first addon or your fiftieth, there's something here for you.

Quality of Life Addons¶

The bread and butter of addon development. These solve small, specific annoyances that affect millions of players every day.

PoisonPal — Rogue Poison Reminder Beginner¶

What it does: Monitors your active poison buffs, warns you when they're missing, and auto-suggests the right poisons based on your current spec and talent build.

Why players want it: Every Rogue has zoned into a dungeon, pulled the first pack, and realized their poisons aren't applied. PoisonPal eliminates that moment of shame with a subtle reminder on screen and a pre-pull check.

Mode: Blizzard Faithful — Pure data monitoring with non-intrusive alerts. No frame replacement, no combat interaction.

Technical approach:

• Register UNIT_AURA, PLAYER_ENTERING_WORLD, and ZONE_CHANGED_NEW_AREA events
• On each trigger, call C_UnitAuras.GetPlayerAuraBySpellID() to check for active lethal and non-lethal poison buffs
• Compare against a lookup table of poison spell IDs per spec (Assassination vs. Subtlety vs. Outlaw)
• Show a small alert frame anchored to UIParent with a fade-in animation when poisons are missing
• Suppress alerts in rest areas and non-combat zones via IsResting()

/wow-create PoisonPal — A rogue poison reminder addon that warns when
poison buffs are missing, suggests correct poisons for current spec,
uses C_UnitAuras.GetPlayerAuraBySpellID and UNIT_AURA, Blizzard Faithful mode

RepairBuddy — Smart Auto-Repair & Vendor Beginner¶

What it does: Automatically repairs all gear when you visit a vendor (using guild funds if available and permitted), auto-sells grey/junk items, tracks cumulative repair costs per session and lifetime, and warns when any equipped item drops below 20% durability.

Why players want it: Repair and junk-selling is pure tedium. Every player does it, nobody enjoys clicking through the vendor UI. RepairBuddy handles it silently and gives you data about where your gold actually goes.

Mode: Blizzard Faithful — Automates existing vendor interactions with zero UI replacement.

Technical approach:

• On MERCHANT_SHOW, call GetRepairAllCost() to check if repairs are needed
• If cost > 0, attempt RepairAllItems(true) for guild repair first, fall back to RepairAllItems(false)
• Iterate all bag slots with C_Container.GetContainerItemInfo(), sell items with quality == 0
• Print a summary to chat: "Repaired (14g 32s) | Sold 7 junk items (2g 88s)"
• Track totals in SavedVariables with per-session and per-character breakdowns
• On PLAYER_EQUIPMENT_CHANGED, scan all 19 inventory slots for low durability and show a warning

/wow-create RepairBuddy — Auto-repair and junk-sell addon with guild
repair support, durability warnings, cost tracking in SavedVariables,
Blizzard Faithful mode

WeeklyWise — Activity Checklist Intermediate¶

What it does: A cross-character weekly activity tracker that monitors Great Vault progress, Mythic+ runs, world boss kills, weekly quest completions, and raid lockouts. Displays a clean checklist showing what's done and what's left — across all your alts.

Why players want it: Players with multiple characters lose track of which alt has capped their Vault, which one killed the world boss, and which still needs a Mythic+ run. WeeklyWise gives you a single dashboard across all characters.

Mode: Enhancement Artist — Custom UI panel that enhances the existing Great Vault and activity tracking systems.

Technical approach:

• Use SavedVariables with a table keyed by UnitGUID("player") to store per-character data
• On PLAYER_LOGIN, snapshot current character's vault progress, M+ history, and lockouts
• On WEEKLY_REWARDS_UPDATE and CHALLENGE_MODE_COMPLETED, refresh vault data
• Build a ScrollFrame-based UI panel showing all characters in rows with checkmark columns
• Calculate reset countdown using C_DateAndTime.GetSecondsUntilWeeklyReset() and display in header
• Register a slash command (/weeklywise or /ww) and Addon Compartment entry for access

/wow-create WeeklyWise — Cross-character weekly activity tracker with
Great Vault progress, M+ history, world boss kills, raid lockouts,
ScrollFrame UI, account-wide SavedVariables, Enhancement Artist mode

Housing Addons — The New Frontier¶

Player housing is Midnight's headline feature, and it comes with an entirely new API surface. The C_Housing and C_HousingPhotoSharing namespaces are brand new — meaning there's almost no competition. If you build a housing addon now, you're first to market.

HomeSnap — Housing Photo Gallery Intermediate¶

What it does: A social housing screenshot browser. Players can capture screenshots of their housing plots, tag them with categories (cozy, gothic, nature, PvP arena), and share them via the C_HousingPhotoSharing API. Other players can browse, rate, and favorite designs — all in-game.

Why players want it: Housing is inherently social and creative. Players want to show off their builds, get inspiration from others, and curate a gallery of favorites. HomeSnap turns housing screenshots from ephemeral moments into a browsable, shareable collection.

Mode: Enhancement Artist — Extends Blizzard's housing photo system with a richer browsing and social experience.

Technical approach:

• Hook into Blizzard's housing UI to add a "Share to HomeSnap" button using hooksecurefunc
• Use C_HousingPhotoSharing to publish and retrieve photos with metadata tags
• Build a grid-view gallery frame with thumbnail previews using Texture widgets
• Implement a tagging system stored in SavedVariables for local categorization
• Add guild-level photo sharing via C_ChatInfo.SendAddonMessage() on the GUILD channel

/wow-create HomeSnap — Housing photo gallery addon using
C_HousingPhotoSharing API, grid thumbnail browser, tagging system,
guild sharing via addon messaging, Enhancement Artist mode

DecorTracker — Housing Decoration Collector Intermediate¶

What it does: A comprehensive decoration collection tracker. Catalogs all 1,690+ housing decorations in the game, shows which ones you own, which are craftable by your professions, which drop from specific bosses or vendors, and highlights the cheapest path to acquire missing ones.

Why players want it: Housing decorations come from dozens of sources — vendors, crafting, drops, achievements, reputation, and the Trading Post. Without a tracker, players have no idea what they're missing or where to get it.

Mode: Enhancement Artist — Collection management UI that enhances the housing decoration browser.

Technical approach:

• On PLAYER_LOGIN, scan all decoration categories and build a complete catalog in memory
• Cross-reference with C_Housing.IsDecorationOwned() to build owned/missing lists
• Group by source type: vendor, crafting, dungeon drop, achievement, reputation, Trading Post
• For craftable items, check if the player's professions can craft them via C_TradeSkillUI
• Build a filterable list UI with search, category tabs, and source-type filters
• Show collection progress as "247 / 1,693" with a progress bar per category

/wow-create DecorTracker — Housing decoration collection tracker,
catalogs all decorations with source info, ownership status, crafting
cross-reference, filterable list UI, Enhancement Artist mode

UI Enhancement Addons¶

These addons demonstrate the "BetterX" pattern at its best: hooking into Blizzard's existing frames to make them look and work better without replacing the underlying secure infrastructure.

BetterCooldowns — Cooldown Manager Skin Intermediate¶

What it does: Enhances Blizzard's built-in Cooldown Manager with cleaner visuals, customizable countdown text, spell-specific color coding, and group-organized cooldown categories. Uses the new Duration objects for Secret Values-safe cooldown display.

Why players want it: Blizzard's Cooldown Manager (introduced in 11.0) shows your ability cooldowns, but the default presentation is minimal. BetterCooldowns adds polish — colored borders by cooldown length, category grouping (offensive / defensive / utility), and configurable text formatting.

Mode: Enhancement Artist — Skins and extends the existing Cooldown Manager frames.

Technical approach:

• Use hooksecurefunc to hook the Cooldown Manager's frame update functions
• On each cooldown frame update, apply custom styling: border color based on remaining time, category icon overlays
• Use C_Spell.GetSpellCooldownDuration() to get Duration objects — never raw seconds
• Pass Duration objects directly to Cooldown:SetCooldownFromDurationObject() for display
• Add a Settings panel for color customization, text format preferences, and category definitions
• Defer all frame modifications behind InCombatLockdown() checks for secure frames

-- Duration-safe cooldown display (Midnight pattern)
local dur = C_Spell.GetSpellCooldownDuration(spellID)
if dur then
    cooldownFrame:SetCooldownFromDurationObject(dur)
end

/wow-create BetterCooldowns — Cooldown Manager enhancement with
Duration objects, spell color coding, category grouping, hooksecurefunc
on Blizzard frames, Enhancement Artist mode

PlateStylist — Nameplate Restyler Advanced¶

What it does: Reskins Blizzard's default nameplates with class-colored health bars, enhanced threat indicators, cast bar improvements, target highlighting, and aura filtering — all without replacing the secure nameplate frames.

Why players want it: Default nameplates are functional but visually bland. PlateStylist makes them information-dense and attractive while keeping the secure frame infrastructure intact. Unlike full nameplate replacements, it survives Blizzard UI updates gracefully.

Mode: Boundary Pusher — Deep hooks into nameplate frames, walking the line between enhancement and replacement.

Technical approach:

• Hook NAME_PLATE_UNIT_ADDED to apply styling when nameplates appear
• Use hooksecurefunc("CompactUnitFrame_UpdateHealth", ...) to restyle after Blizzard updates
• Set health bar color based on UnitThreatSituation() return value (0=grey, 1=yellow, 2=orange, 3=red)
• Add class color via RAID_CLASS_COLORS[select(2, UnitClass(unit))] for player nameplates
• Use UnitHealthPercent() with StatusBar:SetValue() — never extract raw health numbers
• Check frame:IsForbidden() before every modification to avoid taint on protected frames
• Apply cast bar enhancements by hooking CastingBarFrame_OnEvent equivalents

-- Safe nameplate styling (check IsForbidden first)
hooksecurefunc("CompactUnitFrame_UpdateHealth", function(frame)
    if frame:IsForbidden() then return end
    local unit = frame.unit
    if not unit then return end

    local _, class = UnitClass(unit)
    if class and UnitIsPlayer(unit) then
        local color = RAID_CLASS_COLORS[class]
        frame.healthBar:SetStatusBarColor(color.r, color.g, color.b)
    end
end)

/wow-create PlateStylist — Nameplate restyler with class colors, threat
coloring, cast bar enhancement, hooksecurefunc on CompactUnitFrame,
IsForbidden checks, Boundary Pusher mode

BossTimeline+ — Boss Timeline Enhancer Advanced¶

What it does: Enhances Blizzard's native boss ability timeline (new in 12.0) with custom annotations, phase markers, personal cooldown overlay, and historical comparison from previous pulls. Uses the C_EncounterEvents namespace to read boss ability data that Blizzard now exposes natively.

Why players want it: Blizzard added a built-in boss ability timeline in Midnight, but it's minimal. BossTimeline+ layers additional context on top — showing when your defensive cooldowns will be available relative to boss abilities, marking phase transitions, and letting raid leaders annotate the timeline with strategy notes.

Mode: Boundary Pusher — Deeply extends Blizzard's encounter timeline system with overlay frames and custom data layers.

Technical approach:

• Hook Blizzard's encounter timeline frame to add overlay elements using hooksecurefunc
• On ENCOUNTER_START, query C_EncounterEvents.GetEncounterTimeline() for the full ability schedule
• Create a secondary timeline track showing the player's defensive cooldown availability
• Use C_Spell.GetSpellCooldownDuration() to project when cooldowns will be available (Duration objects)
• Store per-boss annotations in SavedVariables keyed by encounter ID
• Share annotations with raid via C_ChatInfo.SendAddonMessage() — only outside encounter lockdown
• On ENCOUNTER_END, snapshot the pull for historical comparison

/wow-create BossTimeline+ — Boss timeline enhancer using
C_EncounterEvents API, personal cooldown overlay with Duration objects,
annotation system, raid sharing via addon comms, Boundary Pusher mode

Social & Economy Addons¶

WoW is an MMO — the best addons enhance the social and economic experience, not just combat.

GuildBoard — Guild Event Coordinator Intermediate¶

What it does: An in-game guild event board where officers can post events (raid nights, M+ groups, housing tours, PvP nights) and members can sign up with role preferences. Think a lightweight in-game calendar enhancement with RSVP tracking.

Why players want it: The built-in calendar is clunky and limited. Discord handles scheduling but requires tabbing out. GuildBoard keeps event coordination where it belongs — inside the game, visible at a glance when you log in.

Mode: Blizzard Faithful — Uses standard addon messaging for data sync. Clean, non-intrusive UI.

Technical approach:

• Officers create events via a simple form frame (title, date, time, description, role slots)
• Serialize event data and broadcast to guild via C_ChatInfo.SendAddonMessage("GuildBoard", data, "GUILD")
• Members receive events and store them in local SavedVariables
• Sign-up responses sent back via addon message with role preference (tank/healer/DPS)
• Display a bulletin board frame with upcoming events sorted by date
• Use MenuUtil.CreateContextMenu() for right-click actions (edit, delete, sign up, withdraw)
• Show a login notification if new events were posted since last session

/wow-create GuildBoard — Guild event board with RSVP system, addon
messaging sync, officer event creation, role sign-ups, bulletin board
UI, Blizzard Faithful mode

CraftCalc — Crafting Profit Calculator Intermediate¶

What it does: Scans your known crafting recipes, cross-references reagent costs from the Auction House, and calculates profit margins for every craftable item. Highlights the most profitable crafts, tracks material price trends, and integrates with the crafting order system.

Why players want it: The crafting economy in WoW is deep but opaque. Players craft items without knowing if they're profitable. CraftCalc turns the crafting UI into a profit dashboard, showing exactly which recipes make gold and which burn it.

Mode: Performance Zealot — Heavy data processing with thousands of recipe and price calculations. Must be fast and memory-efficient.

Technical approach:

• On TRADE_SKILL_SHOW, scan all recipes via C_TradeSkillUI.GetAllRecipeIDs()
• For each recipe, get reagent list via C_TradeSkillUI.GetRecipeSchematic()
• Query AH prices for both reagents and finished products (batch queries to avoid throttling)
• Calculate: profit = sellPrice - sum(reagentCosts) - AH cut (5%)
• Cache price data in SavedVariables with timestamps to avoid excessive AH queries
• Display a sortable table: recipe name, reagent cost, sell price, profit, margin %
• Use C_Timer.NewTicker() to stagger AH queries (max 1 per second to avoid server throttling)
• Highlight recipes with profit > 0 in green, losses in red

/wow-create CraftCalc — Crafting profit calculator with AH price
lookups, reagent cost summation, profit margin display, price caching,
sortable recipe table, Performance Zealot mode

Fun & Novelty Addons¶

Not everything has to optimize your gameplay. These addons add joy, personality, and memorable moments to the game.

AchieveMore — Achievement Progress Dashboard Beginner¶

What it does: A visual achievement progress dashboard that shows your completion percentage across all achievement categories, highlights nearly-complete achievements (90%+ progress), and suggests the easiest ones to finish next based on your current progress.

Why players want it: The default achievement UI is a sprawling tree that's hard to navigate. AchieveMore gives you a bird's-eye view of where you stand and what's low-hanging fruit. Achievement hunters live for that "97% complete" nudge.

Mode: Enhancement Artist — Custom dashboard UI that reads from Blizzard's achievement data.

Technical approach:

• On slash command or Compartment click, scan all achievement categories via GetCategoryList()
• For each category, iterate achievements with GetCategoryNumAchievements() and GetAchievementInfo()
• Calculate completion percentage per category and overall
• For incomplete achievements, check criteria progress to find "almost done" candidates
• Sort near-complete achievements by remaining criteria count (ascending) for the "Finish These" list
• Display as a grid of category cards with progress bars and a "Suggested Next" sidebar
• Cache the scan results for the session — achievements don't change frequently

/wow-create AchieveMore — Achievement progress dashboard with category
completion percentages, near-complete suggestions, progress bar grid,
Enhancement Artist mode

ScreenShotter — Smart Screenshot Automator Intermediate¶

What it does: Automatically captures screenshots at memorable moments — achievement unlocks, level-ups, boss kills, rare mount drops, first-time dungeon completions, and housing milestones. Optionally hides the UI before capturing for clean shots, and logs every screenshot with metadata (date, zone, event type) in SavedVariables.

Why players want it: Years later, players wish they had screenshots of their first Mythic kill or that rare mount drop. ScreenShotter ensures you never miss a moment, building an automatic photo journal of your WoW journey.

Mode: Blizzard Faithful — Pure event monitoring with the built-in Screenshot() function. Zero UI modification.

Technical approach:

• Register all trigger events: ACHIEVEMENT_EARNED, PLAYER_LEVEL_UP, ENCOUNTER_END, NEW_MOUNT_ADDED, CHAT_MSG_LOOT, ZONE_CHANGED_NEW_AREA
• On each trigger, optionally hide UI with UIParent:SetAlpha(0), take screenshot, restore with C_Timer.After(0.1, ...)
• Add a brief delay (C_Timer.After(0.5, Screenshot)) to let the game render the moment properly
• Log each screenshot in SavedVariables: {event, zone, timestamp, mapID}
• Provide a /screenshots command showing the log with filters by event type
• Settings panel for toggling which events trigger screenshots and whether to hide UI
• Throttle screenshots to max 1 per 5 seconds to prevent spam during rapid events

-- Smart screenshot with UI hide
local function SmartScreenshot(eventType)
    if ns.db.hideUI then
        UIParent:SetAlpha(0)
        C_Timer.After(0.1, function()
            Screenshot()
            C_Timer.After(0.1, function()
                UIParent:SetAlpha(1)
            end)
        end)
    else
        Screenshot()
    end
    -- Log metadata
    local map = C_Map.GetBestMapForUnit("player")
    table.insert(ns.db.log, {
        event = eventType,
        mapID = map,
        time = time(),
    })
end

/wow-create ScreenShotter — Smart screenshot automator that captures
on achievements, level-ups, boss kills, mount drops, with UI-hide
option, metadata logging, throttling, Blizzard Faithful mode
