Videolyzer

One continuous timeline for YouTube playlists: unified progress bar with cross-video seeking.

> One timeline for the whole playlist. > Cross-video seeking, hover previews straight from YouTube's own storyboards, > a queue that stays live while you watch. YouTube resets its progress bar at every video boundary. Videolyzer draws one bar over the player covering the entire playlist or queue: two content scripts, one event channel, zero permissions. - **One continuous timeline** — every queue video becomes a segment of a single bar, with ticks at boundaries and a live position across the whole queue - **Cross-video seeking** — click, drag or arrow-key anywhere, including inside videos you haven't reached yet - **Hover previews** — real storyboard frames on the playing video, cover thumbnails for every other segment, title and absolute queue time always visible - **A queue that stays live** — add or remove videos while watching and the bar grows in real time, refereed against the player's own live queue order - **Keyboard first-class** — ←/→ for small steps, Shift for big steps; the bar is an accessible ARIA slider - **Honest guards** — ads freeze the timeline, shuffle disables scrubbing, live streams bow out
