This works very well. It's super fast and responsive. But please add a gun pointing at Clippy that lets the user end him in one, clear action. I otherwise had to keep clicking through to get rid of him.

Your tech choices (WebGPU/WebAudio) make for ultra-fast load times that easily beat Kdenlive (my usual go-to editor) without even needing a download. But have you tried using Tauri to provide a "native" version?
