Problem Description

On YouTube’s website, there is a graph above the timeline that shows the most replayed sections of a video, making it easy to find the most important parts instantly. This feature is especially helpful for long videos, such as interviews, where users may want to quickly locate key highlights without manually scrolling through the entire video. Unfortunately, this functionality is missing in FreeTube, which makes navigation less efficient.

Proposed Solution

Add a graph to FreeTube that displays the most-viewed timestamps of a video, similar to the one on YouTube’s website. This feature would allow users to identify the most important parts of a video instantly. If implementing this feature requires data from YouTube’s API, it would be helpful to explore whether it is technically feasible.

Alternatives Considered

I don't think there are any.

Additional Information

[Nobylo]

The graph can be implemented as a hidden menu, when shown it sits directly underneath the player and still lines up with the seek bar

(mockup)

This works as an alternative in case slapping the graph on top of the moving seekbar is too hard. Whether it should be right side up or upside down is up for debate, in this mockup it's the latter and it's hard to see that. This solution would function just as well as Youtube's solution, but would take up more space and needs to be turned on first

I don't think the local API is able to scrape the relevant information for this yet, if not that would need to be figured out to do this. Ditto for the invidious API(?)
