8. Auto Rewind: Automatically rewind the video by a customizable amount (e.g., 3-5 seconds) whenever you save a word, so you can hear its pronunciation in context again.
9. Auto Slow-mo: Automatically slows down playback speed (e.g., to 0.8x) when a subtitle contains words you marked as "Hard" or are actively reviewing.
10. 🃏 Advanced Spaced Repetition (Anki-Style)
