1) The play button wears your progress as a ring; a practice loop fills its own ring with every pass
2) One glass dock lets the scene show through, and wide films sit on a soft blurred echo of themselves instead of black bars
3) Hold anywhere for 2× and slide to tune it, double-tap to skip, swipe in fullscreen for volume and brightness
4) Ask Orbit (✦): say "too fast and I'm going to bed" and it slows down and sets a sleep timer. It runs in the browser, with no server, and you can undo it

6) It adds what v10 doesn't ship yet: a chapter menu with previews, caption styling, saved preferences, A–B practice loops
7) Every gesture has a button and a key, focus is always visible, and motion calms down on request
