+**Status:** Recommendations for Future Development
+
+---
+
+## Overview
+
+This document provides comprehensive suggestions for additional features, enhancements, and upgrades to evolve the Media Downloader into a world-class media management platform.
+
+---
+
+## Priority 1: Critical Features (High Value, High Impact)
+
+### 1.1 Webhook Integration System
+**Priority:** HIGH | **Effort:** 6-8 hours | **Value:** HIGH
+
+**Description:**
+Allow users to configure webhooks that fire on specific events (downloads completed, errors, etc.) to integrate with other systems.
+
+**Implementation:**
+```python
+# modules/webhook_manager.py
+class WebhookManager:
+    def __init__(self, config: Dict[str, Any]):
+        self.webhooks = config.get('webhooks', [])
+
+    async def fire_webhook(self, event: str, data: Dict[str, Any]):
+        """Send webhook notification to configured endpoints"""
+        matching_webhooks = [w for w in self.webhooks if event in w['events']]
+
+        for webhook in matching_webhooks:
+            try:
+                await self._send_webhook(webhook['url'], event, data, webhook.get('secret'))
+            except Exception as e:
+                logger.error(f"Webhook failed: {e}")
+
+    async def _send_webhook(self, url: str, event: str, data: Dict, secret: Optional[str]):
+        """Send HTTP POST with HMAC signature"""
+        payload = {
+            'event': event,
+            'timestamp': datetime.now().isoformat(),
+            'data': data
+        }
+
+        headers = {'Content-Type': 'application/json'}
+        if secret:
+            signature = self._generate_hmac(payload, secret)
+            headers['X-Webhook-Signature'] = signature
+
+        async with aiohttp.ClientSession() as session:
+            await session.post(url, json=payload, headers=headers, timeout=10)
+```
+
+**Configuration Example:**
+```json
+{
+  "webhooks": [
+    {
+      "name": "Discord Notifications",
+      "url": "https://discord.com/api/webhooks/...",
+      "events": ["download_completed", "download_error"],
+      "secret": "webhook_secret_key",
+      "enabled": true
+    },
+    {
+      "name": "Home Assistant",
+      "url": "http://homeassistant.local:8123/api/webhook/media",
+      "events": ["download_completed"],
+      "enabled": true
+    }
+  ]

+
+### 1.4 User Role-Based Access Control (RBAC)
+**Priority:** MEDIUM | **Effort:** 12-16 hours | **Value:** HIGH
+
+**Description:**
+Implement granular permissions system for multi-user environments.
+
+**Roles:**
+- **Admin** - Full access to everything
+- **Power User** - Can trigger downloads, view all media, modify configurations
+- **User** - Can view media, trigger downloads (own accounts only)
+- **Viewer** - Read-only access to media gallery
+- **API User** - Programmatic access with limited scope
+
+**Permissions:**
+```python
+PERMISSIONS = {
+    'admin': ['*'],
+    'power_user': [
+        'media.view',
+        'media.download',
+        'media.delete',
+        'downloads.view',
+        'downloads.trigger',
+        'config.view',
+        'config.update',
+        'scheduler.view',
+        'scheduler.manage',
+        'analytics.view'
+    ],
+    'user': [
+        'media.view',
+        'media.download',
+        'downloads.view.own',
+        'downloads.trigger.own',
+        'analytics.view'
+    ],
+    'viewer': [
+        'media.view',
+        'analytics.view'
+    ]
+}
+```
+
+**Implementation:**
+```python
+# web/backend/auth_manager.py
+def require_permission(permission: str):
+    """Decorator to check user permissions"""
+    def decorator(func):
+        async def wrapper(*args, current_user: Dict = Depends(get_current_user), **kwargs):
+            if not has_permission(current_user, permission):
+                raise HTTPException(status_code=403, detail="Insufficient permissions")
+            return await func(*args, current_user=current_user, **kwargs)
+        return wrapper
+    return decorator
+
+# Usage
+@app.delete("/api/media/{file_id}")
+@require_permission('media.delete')
+async def delete_media(file_id: str, current_user: Dict = Depends(get_current_user)):
+    # Only users with media.delete permission can access
+    pass
+```
+

+
+## Priority 2: Performance & Scalability (High Impact)
+
+### 2.1 Redis Caching Layer
+**Priority:** MEDIUM | **Effort:** 8-10 hours | **Value:** MEDIUM
+
+**Description:**

+import redis
+import json
+from typing import Optional, Any
+
+class CacheManager:
+    def __init__(self, redis_url: str = 'redis://localhost:6379'):
+        self.redis = redis.from_url(redis_url, decode_responses=True)
+
+    def get(self, key: str) -> Optional[Any]:
+        """Get cached value"""
+        value = self.redis.get(key)
+        return json.loads(value) if value else None
+
+    def set(self, key: str, value: Any, ttl: int = 300):
+        """Set cached value with TTL"""
+        self.redis.setex(key, ttl, json.dumps(value))
+
+    def delete(self, key: str):
+        """Delete cached value"""
+        self.redis.delete(key)
+
+    def clear_pattern(self, pattern: str):
+        """Clear all keys matching pattern"""
+        for key in self.redis.scan_iter(pattern):
+            self.redis.delete(key)
+
+# Usage in API
+@app.get("/api/stats")
+async def get_stats():
+    cache_key = "stats:global"
+    cached = cache_manager.get(cache_key)
+
+    if cached:
+        return cached
+
+    # Compute expensive stats
+    stats = compute_stats()
+
+    # Cache for 5 minutes
+    cache_manager.set(cache_key, stats, ttl=300)
+
+    return stats
+```
+
+**Benefits:**

+
+@celery_app.task
+def generate_thumbnail(file_path: str) -> str:
+    """Generate thumbnail in background"""
+    thumbnail_path = create_thumbnail(file_path)
+    return thumbnail_path
+
+@celery_app.task
+def process_batch_download(urls: List[str], platform: str, user_id: int):
+    """Process batch download asynchronously"""
+    results = []
+    for url in urls:
+        try:
+            result = download_media(url, platform)
+            results.append({'url': url, 'status': 'success', 'file': result})
+        except Exception as e:
+            results.append({'url': url, 'status': 'error', 'error': str(e)})
+
+    # Notify user when complete
+    notify_user(user_id, 'batch_complete', results)
+    return results
+
+# Usage in API
+@app.post("/api/batch-download")
+async def batch_download(urls: List[str], platform: str):
+    task = process_batch_download.delay(urls, platform, current_user['id'])
+    return {'task_id': task.id, 'status': 'queued'}
+
+@app.get("/api/tasks/{task_id}")
+async def get_task_status(task_id: str):
+    task = celery_app.AsyncResult(task_id)
