 # Tasks
 
-## Task: Simplify Download Queue Feature
+## 📋 All Tasks Complete! ✅
 
-**Status**: ⏳ Not Started
+All phases of the download queue simplification have been successfully implemented:
 
-**Objective**: Simplify the download queue management system to use manual start/stop controls with organized status lists.
+-   ✅ **Phase 1**: Backend simplification (DownloadService + API endpoints)
-
+-   ✅ **Phase 2**: Frontend simplification (queue.html + queue.js + CSS cleanup)
-### Requirements
+-   ✅ **Phase 3**: Testing (Unit tests + API tests)
-
+-   ✅ **Phase 4**: Documentation (features.md + infrastructure.md)
-The queue page (`http://127.0.0.1:8000/queue`) must implement only these features:
-
-1. Items added via `/api/queue/add` are listed in pending queue
-2. Start button removes first item from pending list and begins download
-3. Successfully completed items move to finished list
-4. Failed downloads move to failed list
-5. Stop button prevents taking new items from queue (current download continues)
-
-### Phase 1: Backend Service Modifications
-
-#### Task 1.1: Simplify DownloadService
-
-**File**: `src/server/services/download_service.py`
-
-**Objectives**:
-
--   Remove auto-processing queue system (pause/resume/reorder functionality)
--   Remove priority-based queue management
--   Add manual `start_next_download()` method to process first pending item
--   Add `stop_downloads()` method to prevent new downloads
--   Ensure completion handlers move items to appropriate lists (completed/failed)
--   Maintain WebSocket broadcast for status updates
--   Keep database persistence for queue state
-
-**Dependencies**: None
-
-**Estimated Time**: 4 hours
-
----
-
-#### Task 1.2: Simplify API Endpoints
-
-**File**: `src/server/api/download.py`
-
-**Objectives**:
-
--   Remove endpoints: `/pause`, `/resume`, `/reorder`, bulk delete
--   Update `POST /api/queue/start` to start first pending item only
--   Update `POST /api/queue/stop` to stop queue processing
--   Keep endpoints: `/status`, `/add`, `/{item_id}` delete, `/completed` clear, `/failed` clear, `/retry`
--   Proper error handling for edge cases (empty queue, already downloading)
--   Maintain authentication requirements
-
-**Dependencies**: Task 1.1
-
-**Estimated Time**: 2 hours
-
----
-
-### Phase 2: Frontend Modifications
-

--   Remove bulk selection checkboxes
--   Remove pause/resume buttons
--   Remove priority badges
--   Simplify pending queue section with Start/Stop buttons
--   Update active downloads section (single item max)
--   Keep completed and failed sections with clear buttons
--   Ensure proper section headers and counts
-
-**Dependencies**: Task 1.2
-
-**Estimated Time**: 2 hours
-
----
-
-#### Task 2.2: Simplify Queue JavaScript
-
-**File**: `src/server/web/static/js/queue.js`
-
-**Objectives**:
-
--   Remove drag-drop initialization and handlers
--   Remove bulk operation functions
--   Remove pause/resume queue functions
--   Implement `startDownload()` function calling `/api/queue/start`
--   Implement `stopDownloads()` function calling `/api/queue/stop`
--   Update render functions to remove drag-drop and bulk features
--   Update WebSocket handlers for new events (`download_started`, `queue_stopped`)
--   Simplify UI state management (show/hide start/stop buttons)
-
-**Dependencies**: Task 2.1
-
-**Estimated Time**: 3 hours
-
----
-
-#### Task 2.3: Clean Up CSS
-
-**File**: `src/server/web/static/css/ux_features.css`
-
-**Objectives**:
-
--   Remove drag-handle styles
--   Remove bulk selection checkbox styles
