Current features:

• Support "offline mode" - browse your archive even if external hard drives are disconnected at the moment
• Supports indexing of Video files with animated thumbnails
• Telegram connector - automatically download to your archive photos that your friends share with you
• Extensive image formats support thanks to libvips library
• Extensive video file formats support thanks to ffmpeg
