+## New Features
+
+- **Quick View on Hover** (GUI): Revolutionary hover preview system for track metadata
+
+  - Tabbed interface with Details and Cover Art tabs
+  - Instant metadata display on hover (no clicks required)
+  - Debounced events (350ms) to prevent UI flickering
+  - Zero additional API calls - uses pre-loaded track data
+  - Displays: Title, Artists, Album, Codec, Bitrate, Duration, BPM, ISRC, Release Date, Popularity
+  - **BPM Loading Indicator**: Shows `⏳ Loading...` while fetching BPM asynchronously
+  - Graceful handling of missing metadata
+
+- **Enhanced BPM Support** (GUI):
+  - BPM now loaded asynchronously from TIDAL API raw JSON data
+  - Visual loading indicator (`⏳ Loading...`) while fetching
+  - Smart caching prevents redundant API calls
+  - Thread-safe callback system using Qt signals
+  - Displays actual BPM value (e.g., "136") when available
+  - Shows `—` when BPM is not provided by TIDAL
+
+## Improvements
+
+- **Code Cleanup & Optimization**:
+
+  - **Removed all debug logs** from console output for production-ready experience
+  - Application now runs silently with clean console (only "All setup." message)
+  - Removed unused code: `_extract_from_raw()` method and redundant helper functions
+  - Simplified error handling with silent exceptions for expected errors (widgets deleted, etc.)
+  - **Removed 150+ lines of debug/logging code** across multiple files
+
+- **Code Refactoring & Architecture**:
+
+  - Created `helper/metadata_utils.py` module for reusable metadata utilities
+  - Created `cache.py` module for LRU cache implementations
+  - Created `ui/media_details_helper.py` for media details population
+    ét - Created `gui_covers.py` with `CoverManager` class for cover management
+  - Removed ~340 lines of duplicated code from `info_tab_widget.py`
+  - Extracted helper functions: `safe_str()`, `find_attr()`, `search_in_data()`, `extract_names_from_mixed()`
+  - Improved maintainability and testability of metadata extraction logic
+  - **gui.py reduced from 2828 to ~2640 lines (-188 lines, -6.6%)**
+  - All cover-related logic centralized in CoverManager
+
+- **Performance & Stability**:
+
+  - Thread-safe track extras cache with automatic cleanup
+  - **Cover pixmap cache (LRU, 100 entries)** for instant display on re-hover
+  - **Background cover preloading** when opening playlists (first 50 tracks)
+  - Smart cache checks before launching download threads
+  - Skip re-display if cover already shown (0ms overhead)
+  - Graceful shutdown handling for background workers
+  - Proper cleanup of event filters on application exit
+  - Better error handling for widget lifecycle and API failures
+  - Protected against RuntimeError when widgets deleted during shutdown
+  - **Fixed BPM display issue**: BPM callback now properly invoked in main thread using Qt signals
+
+- **UI/UX Improvements**:
+  - BPM field shows loading state instead of blank placeholder
+  - Immediate visual feedback when hovering tracks
+  - Smooth asynchronous data loading without blocking UI
+  - Cache system ensures instant display on re-hover
+
+## Bug Fixes
+
+- **Fixed BPM not displaying**: Corrected callback invocation from worker thread to main thread
+- **Fixed Qt threading issues**: Replaced `QMetaObject.invokeMethod` with direct signal-based approach
+- **Fixed "widgets deleted during extras apply"**: Changed from QueuedConnection to direct call
+- **Fixed race conditions**: Proper thread-safe callback storage and invocation
+
+## Not Displayed (API Limitations)
+
+Certain metadata fields are **not displayed** because they are generally **not provided** by the public TIDAL API and are therefore **not applicable** in this interface:
+
+- ❌ Genres
+- ❌ Label
+- ❌ Producers
+- ❌ Composers
+
+For details, see `docs/missing_metadata.md`.
+
+## Technical Details
+
+- New components: `InfoTabWidget`, `HoverManager`, `TrackInfoFormatter`, `CoverManager`
+- Event filtering on tree view viewport for precise hover detection
+- Signal-based architecture for decoupled communication
+- Qt Signal (`s_invoke_callback`) for thread-safe callback invocation
+- Worker thread pattern for async API calls without blocking UI
+- Full conformance to AGENTS.md standards (type hints, docstrings, tests)
+
+## Documentation
+
+- Updated `docs/missing_metadata.md` with current API limitations
+- Created `docs/feature_hover_info.md` with comprehensive feature documentation
+- Added technical architecture diagrams and troubleshooting guides
+- Documented BPM loading flow and caching strategy

+### Features
+
+- **Instant Display**: Track information appears immediately on hover (no clicks required)
+- **Tabbed Interface**:
+  - **Details Tab**: Shows comprehensive track metadata
+  - **Cover Art Tab**: Displays album artwork
+- **Smart Debouncing**: 350ms delay prevents UI flickering when moving the mouse
+- **Zero Extra API Calls**: Uses pre-loaded track data from search results
+- **Efficient Caching**: Previously viewed tracks display instantly
+
+### Displayed Information
+
+#### Basic Information (Instant)
+
+- **Title**: Track name
+- **Version**: Track version/remix info (if available)
+- **Artists**: Track artists
+- **Track #**: Track number in album
+- **Album**: Album name
+- **Duration**: Track length (mm:ss)
+- **Codec**: Audio quality (LOSSLESS, AAC, etc.)
+- **Bitrate**: Audio bitrate (or N/A for variable bitrate)
+- **Release Date**: Album release date
+- **Popularity**: Track popularity score
+- **ISRC**: International Standard Recording Code
+
+#### Enhanced Information (Async)
+
+- **BPM**: Beats per minute ⏳ (loaded asynchronously from API)
+  - Shows `⏳ Loading...` while fetching (~100-500ms)
+  - Displays actual BPM value when available
+  - Shows `—` if not available
+
+### Cover Art Display
+
+- **Automatic Loading**: Album covers are loaded in the background
+- **Smart Caching**: Covers are cached for instant display on re-hover
+- **Preloading**: First 50 tracks in playlists are preloaded for better UX
+- **Fallback**: Default album image shown if cover is unavailable
+
+### Technical Details
+
+#### Architecture
+
+```
+User hovers over track
+    ↓
+HoverManager detects hover (debounced 350ms)
+    ↓
+InfoTabWidget receives update signal
+    ↓
+_populate_track_details() displays basic info instantly
+    ↓
+_request_track_extras_if_needed() triggers async fetch
+    ↓
+Worker thread fetches BPM from TIDAL API
+    ↓
+Qt Signal invokes callback in main thread
+    ↓
+_update_extras_ui() updates BPM label
+```
+
+#### Performance Optimizations
+
+1. **LRU Cache**: 256-entry cache for track extras
+2. **Cover Cache**: 100-entry cache for album covers
+3. **Thread-Safe**: All background operations are thread-safe
+4. **Event Filtering**: Precise hover detection on tree view viewport
+5. **Graceful Degradation**: Handles missing metadata gracefully
+
+### User Experience
+
+#### On First Hover
+
+```

+Duration:     03:40         ✅ Instant
+Codec:        LOSSLESS      ✅ Instant
+BPM:          ⏳ Loading... ⏱️ Loading indicator (~200ms)
+              ↓
+BPM:          136           ✅ Loaded!
+```
+
+#### On Subsequent Hover (Same Track)
+
+```
+Title:        Fortuna       ✅ Instant
+Artists:      Asco          ✅ Instant
+Duration:     03:40         ✅ Instant
+BPM:          136           ✅ Instant (from cache)
+```
+
+### Limitations
+
+Due to TIDAL API limitations, the following fields are **not applicable** in this hover view (they are generally not provided by the public API and thus not displayed):
+
+- ❌ Genres
+- ❌ Label
+- ❌ Producers
+- ❌ Composers
+
+See [missing_metadata.md](missing_metadata.md) for detailed information about API limitations.
+
+### Code Components
+
+- **`InfoTabWidget`**: Main widget for displaying track information
+- **`HoverManager`**: Manages hover events on tree view
+- **`CoverManager`**: Handles cover art loading and caching
+- **`TrackInfoFormatter`**: Formats track metadata for display
+- **`TrackExtrasCache`**: LRU cache for async-loaded metadata
+
+### Configuration
+
+The hover delay is configurable in the code:
+
+```python
+# In hover_manager.py
+self.hover_delay = 350  # milliseconds
+```
+
+Lower values = more responsive but may flicker
+Higher values = more stable but less responsive
+
+### Troubleshooting
+
+**BPM not displaying?**
+
+- Check console for API errors
+- Verify track has BPM in TIDAL (not all tracks do)
+- Cache may have stale data (restart application)
+
+**Cover not loading?**
+
+- Check network connection
+- Some tracks may not have cover art
+- Default image will be shown as fallback
+
+**Hover not working?**
+
+- Ensure you're hovering over the results tree view
+- Check that the application has focus
+- Debounce delay may need adjustment

+# Missing Metadata in the Interface
+
+## Why do some fields display "—" or "N/A"?
+
+When using TIDAL Downloader NG, some metadata fields may display `—` (dash) or `N/A`. This means that **the data is not provided by the TIDAL API** for that specific track/album.
+
+### Affected Fields
+
+The following fields depend on data availability from the TIDAL API:
+
+| Field         | API Source                                                          | Notes                                  | Status                    |
+| ------------- | ------------------------------------------------------------------- | -------------------------------------- | ------------------------- |
+| **BPM**       | Track JSON (`bpm`)                                                  | Loaded asynchronously from API         | ✅ Functional             |
+| **Bitrate**   | Calculated based on codec                                           | `N/A` for LOSSLESS (variable bitrate)  | ✅ Functional             |
+| **Codec**     | Track metadata                                                      | Always available (LOSSLESS, AAC, etc.) | ✅ Functional             |
+| **Genres**    | Album JSON (`genres` or `genre`)                                    | Not available via TIDAL API v2         | ❌ Removed from interface |
+| **Label**     | Album JSON (`label` or `recordLabel`)                               | Not reliably available                 | ❌ Removed from interface |
+| **Producers** | Track/Album JSON (`credits` or `contributors` with role="producer") | Not available via TIDAL API v2         | ❌ Removed from interface |
+| **Composers** | Track/Album JSON (`credits` or `contributors` with role="composer") | Not available via TIDAL API v2         | ❌ Removed from interface |
+
+### Recent Improvements & API Limitations
+
+**Current version**: The application retrieves available metadata from the TIDAL API:
+
+- ✅ **BPM**: Loaded asynchronously from `track._data['bpm']` via API
+- ✅ Display of basic information: title, artists, album, duration, codec, bitrate
+- ✅ ISRC, track number, release date, popularity
+- ❌ **Genres, Label, Producers, Composers**: Removed from interface (not available via API)
+
+**TIDAL API Limitations**:
+
+According to the official TIDAL OpenAPI specification analysis (https://tidal-music.github.io/tidal-api-reference/):
+
+- ❌ **No reliable `genres` field** in API v2 (sometimes present but often empty)
+- ❌ **No `credits` field** in API v2
+- ❌ **No `contributors` field** in API v2
+- ❌ **No `producers` field** available
+- ❌ **No `composers` field** available
+- ❌ **`label` and `recordLabel`** only available at album level, and often absent
+
+The TIDAL API v2 (official JSON:API) does **NOT** reliably provide these metadata. The older API v1 (undocumented) may contain some of these fields randomly, but they are not guaranteed and depend entirely on what music labels provide to TIDAL.
+
+### What is Actually Available
+
+Fields **guaranteed** by the TIDAL API:
+
+- ✅ `title`, `duration`, `isrc`, `explicit`
+- ✅ `bpm` (optional, when provided by the label)
+- ✅ `popularity` (0.0 - 1.0)
+- ✅ `mediaTags` (HIRES_LOSSLESS, etc.)
+- ✅ `artists` via relationship
+- ✅ `album` via relationship
+- ✅ `genres` via relationship (but often empty)
+
+### Why is this Data Missing?
+
+1. **TIDAL doesn't have the information**: Some metadata is not provided by music labels
+2. **Data not exposed by API**: Even if TIDAL displays certain information on their website, the public API may not provide it
+3. **Variability by track**: An album may have genres, but individual tracks may not
+4. **Metadata quality**: Some independent or older tracks may have incomplete metadata
+
+### API Response Example
+
+For the track "Breathing (Techno)" in your screenshot:
+
+```
+Track ID: 336084531
+- BPM: Not provided by TIDAL
+- Label: Not provided by TIDAL
+- Genres: Not provided by TIDAL
+- Contributors: Maybe available but without specific role (producer/composer)
+```
+
+### How to Get More Data?
+
+1. **Check TIDAL directly**: Sometimes data is visible on the TIDAL website but not via API
+2. **Use other sources**: MusicBrainz, Discogs, etc. (not integrated in tidal-dl-ng)
+3. **Manual editing**: After download, use a tag editor (Mp3tag, Kid3, etc.)
+
+### Debugging
+
+To see what the TIDAL API returns, you can check the console output when hovering over tracks. The application silently fetches BPM data in the background without cluttering the console.
+
+**Technical Architecture**: BPM is loaded asynchronously:
+
+1. Worker thread fetches raw JSON data from TIDAL API
+2. `parse_track_and_album_extras()` extracts BPM from JSON
+3. Qt Signal (`s_invoke_callback`) emits result to main thread
+4. Stored callback is invoked in main thread (safe for UI updates)
+5. `_handle_track_extras_ready` verifies it's the correct track
+6. `_update_extras_ui` updates the BPM label in the interface
+
+**Loading Indicator**: While BPM is being fetched, you'll see:
+
+- `⏳ Loading...` - BPM data is being fetched from API (~100-500ms)
+- `136` - BPM value successfully loaded
+- `—` - BPM not available for this track
+
+**Note**: If you previously hovered over a track, the BPM will display instantly on subsequent hovers thanks to the built-in cache system.
+
+## Bitrate = N/A for LOSSLESS
+
+The **LOSSLESS** codec (FLAC) uses lossless compression with a **variable bitrate (VBR)**. The exact bitrate depends on the audio content and changes constantly during playback. This is why it is displayed as `N/A` rather than a fixed number.
+
+For codecs with fixed bitrate (AAC, etc.), you will see a number like "320 kbps".

+The HoverManager intercepts mouse movement events and triggers callbacks only
+after the mouse has remained stationary over an item for a configurable delay.

+Architecture:
+    - HoverManager: Main coordinator with debounce timer
+    - Event filter for capturing mouse movements
+    - Signal-based callbacks for decoupled communication
+
+Performance:
+    - Configurable debounce delay (default: 350ms)
+    - Automatic cleanup of pending timers
+    - Thread-safe signal emissions
