 ## Features
 
+### PNG Screenshots
+
+Saves screenshots as compressed PNG files instead of the default uncompressed TGA format. Runs on a background thread with no frame drops.
+
+Controlled via the `screenshotQuality` CVar (saved to config.wtf):
+
+- `/script SetCVar("screenshotQuality", "6")` -- set compression level (1 = fast, 9 = smallest, default 6)
+- `/script SetCVar("screenshotQuality", "0")` -- disable PNG, use original TGA format
+
+**DLL:** `pngscreenshots.dll`

 ### Transmog Fix
 
 Eliminates FPS drops caused by rapid equipment visual updates when transmogged items lose durability. No configuration needed, install and forget.

+### Utility Minimap Trackings
+
+Adds TBC/WotLK-style minimap tracking icons for NPC types, game objects, and quest givers.
+Replaces the native tracking dropdown with a combined menu showing both spell tracking and NPC category tracking.
+Can be disabled from the normal AddOn menu. Preferences saved per-character.
+
+- Click the minimap tracking icon to open the dropdown
+- Check/uncheck NPC categories to toggle their minimap icons
+- Spell tracking (Hunter tracking, Find Herbs, etc.) remains available alongside NPC tracking
+- "Hide in Cities" toggle suppresses NPC icons in capital cities
+
+Tracks various npc types and useful objects like Oranges and Brainwasher and Mailbox.
+
+**DLL:** `minimapicons.dll`
+
+---
+
+### Clickthrough
+
+Makes interactable objects and NPCs clickable through players and units that are blocking them. When you click a player or unit that's standing on top of a vendor, mailbox, or other interactable target, the click passes through to the target behind them.
+
+- Players blocking interactable NPCs (vendors, trainers, flight masters, bankers, quest givers, etc.) or game objects become transparent to clicks
+- Players blocking lootable corpses become transparent to clicks
+- Units (pets, NPCs) blocking interactable game objects become transparent to clicks
+- Disabled inside battlegrounds to prevent targeting objectives through enemy players

+### Performance
+
+Engine-level optimizations that reduce CPU time on math, rendering helpers, file lookups, and data decompression. No visual difference, no configuration needed. Included in `weirdutils.dll`.
+
+- **SIMD Math** - replaces 20+ internal math functions with SSE/AVX equivalents covering skeletal animation, particle rendering, frustum culling, collision detection, text glyph caching, and float-to-integer conversion
+- **Data Decompression** - swaps the game's 2004-era zlib with a modern library (2.2x faster). Loading screen times reduced by at least 13%
+- **MPQ File Cache** - caches archive file lookups so repeat file opens skip the archive chain walk. Saving 50-160ms every 15 seconds during heavy gameplay
+- **Timer Calibration** - recalibrates the OS performance counter for accurate animation timing. Ported from [VanillaFixes](https://github.com/hannesmann/vanillafixes)
+
+Most noticeable in cities, raids, and during zone transitions.

+### Version Query API
+
+WeirdUtils registers a Lua global table and query function for addon developers to detect which modules are loaded and their versions. Available from the login screen onward.
+
+#### `GetWeirdUtilsVersion()`
+
+Returns the `WeirdUtils` table containing all enabled modules and their version strings:
+
+```lua
+local modules = GetWeirdUtilsVersion()
+for name, version in pairs(modules) do
+    print(name .. " v" .. version)
+end
+```
+
+#### `GetWeirdUtilsVersion("modulename")`
+
+Returns the version string for a specific module, or `nil` if not loaded:
+
+```lua
+if GetWeirdUtilsVersion("minimapicons") then
+    -- Minimap Icons is available
+end
+
+local ver = GetWeirdUtilsVersion("weirdperformance")  -- "1.0" or nil
+```
+
+The `WeirdUtils` table is additive - if multiple independent DLLs are loaded (e.g. `minimapicons.dll` and `clickthrough.dll` separately), each adds its own modules to the shared table.
+
+---
 
 ### Module Mutexes
 
-Each module also holds a named mutex while active: `Local\WeirdUtils_<name>_<PID>` (e.g. `Local\WeirdUtils_bigcursor_12345`). The exception is transmogfix, which uses `Local\TransmogCoalesceHook_<PID>` for legacy reasons.
+Each module also holds a named mutex while active: `Local\WeirdUtils_<name>_<PID>` (e.g. `Local\WeirdUtils_transmogfix_12345`). The exception is transmogfix, which uses `Local\TransmogCoalesceHook_<PID>` for legacy reasons.
 
 If you see the mutex, the module is loaded - and can use the Runtime Module Control API to disable it. If you don't see it, the module isn't active and you're free to hook those functions yourself.
