FocusSub: Displays one-sentence summary subtitles. Idea: When subtitles are enabled, show a short summary (one sentence) for each segment to help users quickly grasp the content. Features: Parses subtitles (SRT/VTT) and automatically generates a short summary sentence from the most recent subtitle sentence (if not using AI, it takes the prefix/shortens the sentence). Simplicity: Simple → Medium (AI not required).
