An AddOn for World of Warcraft: Vanilla (1.12.1) and The Burning Crusade (2.4.3), which aims to be a full replacement for the original interface. The design is inspired by several screenshots I've seen from TukUI, ElvUI and others. This addon delivers modern features and a minimalistic style that's easy to use right from the start. It is entirely written from scratch without any inclusion of third-party addons or libraries.
This is **not** an addon-pack like [ShaguUI](http://shagu.org/ShaguUI/), however, there is support for external addons like MobHealth3, DPSMate and others, but they will never be shipped within the package.

## What's New in Version 6.0.0 (January 5, 2026)
### 🚀 Major Performance Improvements
- ✅ **Central Raid/Party Event Handler** - Replaced per-frame event registration with a centralized system using O(1) unitmap lookups instead of O(n) iteration. Reduces event processing from ~5,760 calls/sec to ~400 calls/sec in 40-man raids (97.5% improvement)
- ✅ **Raid HP/Mana Update Fix** - Fixed race condition where unitmap wasn't rebuilt after frame IDs were reassigned, causing HP/Mana bars to not update when players swap positions
- ✅ **OnUpdate Throttling** - Added configurable throttles to reduce CPU usage:
- Nameplates: 0.1s throttle (target updates remain instant)
- Tooltip cursor following: 0.1s throttle
- Chat tab mouseover: 0.1s throttle
- Panel alignment: 0.2s throttle
- Autohide hover check: 0.05s throttle
- Libpredict cleanup: 0.1s throttle
### 🔧 Castbar & Pushback System
- ✅ **Pushback Fix** - Fixed spell pushback calculation: now correctly adds delay to `casttime` instead of `start` time, matching actual WoW behavior
- ✅ **Player GUID Caching** - Caches player GUID on PLAYER_ENTERING_WORLD for efficient self-cast detection
- ✅ **Hybrid Detection System** - Uses libcast.db for player casts (handles SPELLCAST_DELAYED events) and SuperWoW's UNIT_CASTEVENT for NPC/other player casts
- ✅ **2-Decimal Precision** - Castbar timer now displays with 2 decimal places (e.g., "1.45 / 2.50") for more precise timing
### 🐱 Druid Stealth Detection
- ✅ **Event-Based Detection** - Replaced polling-based stealth detection with event-driven system using UNIT_CASTEVENT and PLAYER_AURAS_CHANGED
- ✅ **Instant Cat Form Detection** - Detects Cat Form via UNIT_CASTEVENT (spell ID 768) for immediate actionbar page switch
- ✅ **Smart Buff Scanning** - Only scans buffs when actually needed (entering Cat Form), eliminates 31-buff scan every frame
- ✅ **Cached Variables** - Caches stealth state to prevent redundant checks
### 🎯 Nameplate Improvements
- ✅ **Friendly Player Classification** - Fixed friendly players being classified as FRIENDLY_NPC, now correctly uses FRIENDLY_PLAYER for proper nameplate coloring and behavior
- ✅ **Performance Throttle** - 0.1s update throttle for non-target nameplates while keeping target nameplate updates instant
### 🆕 New Modules
- ✅ **nampower.lua** - Nampower DLL integration module:
- Spell Queue Indicator (shows queued spell icon near castbar)
- GCD Indicator

- Distance-based features
- Requires [UnitXP_SP3 DLL](https://codeberg.org/konaka/UnitXP_SP3)

## FAQ
**What does "pfUI" stand for?**
The term "*pfui!*" is german and simply stands for "*pooh!*", because I'm not a
big fan of creating configuration UI's, especially not via the Wow-API
(you might have noticed that in ShaguUI).
**How can I donate?**
You can donate via [GitHub](https://github.com/sponsors/shagu) or [Ko-fi](https://ko-fi.com/shagu)
**How do I report a Bug?**
Please provide as much information as possible in the [Bugtracker](https://github.com/shagu/pfUI/issues).
If there is an error message, provide the full content of it. Just telling that "there is an error" won't help any of us.
Please consider adding additional information such as: since when did you got the error,
does it still happen using a clean configuration, what other addons are loaded and which version you're running.
When playing with a non-english client, the language might be relevant too. If possible, explain how people can reproduce the issue.
**How can I contribute?**
Report errors and issues in the [Bugtracker](https://github.com/shagu/pfUI/issues).
Please make sure to have the latest version installed and check for conflicting addons beforehand.
**I have bad performance, what can I do?**
Version 6.0.0 includes significant performance optimizations. If you still experience issues:
1. Disable "Frame Shadows" in Settings → Appearance → Enable Frame Shadows
2. Check `/pfdll` to see which DLLs are active (some features require DLLs)
3. Disable all AddOns but pfUI and enable one-by-one to identify conflicts
4. Report issues via the [Bugtracker](https://github.com/shagu/pfUI/issues)
**Where is the happiness indicator for pets?**
The pet happiness is shown as the color of your pet's frame. Depending on your skin, this can either be the text or the background color of your pet's healthbar:
- Green = Happy
- Yellow = Content
- Red = Unhappy
Since version 4.0.7 there is also an additional icon that can be enabled from the pet unit frame options.
**Can I use Clique with pfUI?**
This addon already includes support for clickcasting. If you still want to make use of clique, all pfUI's unitframes are already compatible to Clique-TBC. For Vanilla, a pfUI compatible version can be found [Here](https://github.com/shagu/Clique/archive/master.zip). If you want to keep your current version of Clique, you'll have to apply this [Patch](https://github.com/shagu/Clique/commit/a5ee56c3f803afbdda07bae9cd330e0d4a75d75a).
**Where is the Experience Bar?**
The experience bar shows up on mouseover and whenever you gain experience, next to left chatframe by default. There's also an option to make it stay visible all the time.
**How do I show the Damage- and Threatmeter Dock?**
If you enabled the "dock"-feature for your external (third-party) meters such as DPSMate or KTM, then you'll be able to toggle between them and the Right Chat by clicking on the ">" symbol on the bottom-right panel.
**Why is my chat always resetting to only 3 lines of text?**
This happens if "Simple Chat" is enabled in blizzards interface settings (Advanced Options).
Paste the following command into your chat to disable that option: `/run SIMPLE_CHAT="0"; pfUI.chat.SetupPositions(); ReloadUI()`
**How can I enable mouseover cast?**
On Vanilla, create a macro with "/pfcast SPELLNAME". If you also want to see the cooldown, You might want to add "/run if nil then CastSpellByName("SPELLNAME") end" on top of the macro. For The Burning Crusade, just use the regular mouseover macros.
**Will there be pfUI for Activision's "Classic" remakes?**
No, it would require an entire rewrite of the AddOn since the game is now a different one. The AddOn-API has evolved during the last 15 years and the new "Classic" versions are based on a current retail gameclient. I don't plan to play any of those new versions, so I won't be porting any of my addons to it.
**Everything from scratch?! Are you insane?**
Most probably, yes.
