A robust, cross-platform GUI application built with Python and PyQt6 for managing, editing, and organizing M3U/M3U8 playlists. Optimized for performance and security.

• Playlist Management: Load and save M3U playlists with support for standard #EXTINF metadata (Group, Logo, Name, Duration).
• Load from URL: Download and edit playlists directly from a web link with a dedicated Reload button for quick refreshes.
• Performance Optimized:
  • Fast Parsing: High-performance M3U parser for near-instant loading of large playlists.
  • Efficient Undo/Redo: Delta-based undo system reduces memory overhead.
  • Throttled Logo Loading: Background logo fetching with targeted UI updates for smooth scrolling.
• Enhanced Stream Preview:
  • Live Playback: Interactive video preview with full playback controls (Play/Pause, Stop, Volume, Fullscreen).
  • Navigation: Browse through channels directly within the preview window using Next/Previous buttons.
  • Integrated Storyboard: Generate and view frame-by-frame storyboards of your streams.
  • Live Editing: Edit the channel's group directly from the preview screen with real-time synchronization.
• Stream Security Audit:
  • Comprehensive Scanning: Audit streams for SSL/TLS validity, content-type correctness, and suspicious redirects.
  • Reputation Check: Identify streams from known malicious or low-reputation domains.
  • Visual Indicators: Color-coded security status (Green Shield for secure, Warning for insecure) with detailed tooltips.
• Smart Organization:
  • Advanced Smart Grouping: Regex-based categorization with resolution (4K, HD, SD) and country detection.
  • Manage Groups: Dedicated dialog to bulk rename, add, or delete groups across the entire playlist.
  • Drag and Drop: Reorder channels easily by dragging rows.
  • Context Menu: Quick "Edit Group" and "Open in VLC" actions.
• Health Check: Validate stream URLs via asynchronous HTTP HEAD requests with granular feedback.
• Search & Filter: Real-time search and group-based filtering.
• Export: Export playlists to CSV format.
• Dark Mode: Sleek, modern dark theme for reduced eye strain.
