Session Timeline

The session timeline is the player's time bar that lays the whole session on a single axis from start to end and marks the notable moments along it.

The timeline is what turns watching a replay from “sitting through a long video” into “jumping straight to the moment that matters.” Without it, an analyst has to watch the whole session to reach the problem; with it, the points where notable behavior occurred are highlighted on the bar and you can jump right there. Its real value shows on long sessions: a ten-minute session may have only three important seconds, and the timeline finds those three seconds. But a timeline is only as useful as the signals placed on it; if the tool cannot detect a rage click, an error or a quick back, the bar stays bare and everything must be scrubbed by hand again.
