Thanks for this awesome project - the timeline editing and multi-track support are really well done!
The ask: AI-powered synchronization between audio tracks and subtitle text elements.
Why it would be valuable: Auto-sync subtitles to speech timing (no manual alignment), huge time saver for content creators, accessibility compliance for enterprise users, and a popular feature in competitors like CapCut (which you're already inspired by). Could leverage Whisper or similar for transcription + timing.
