This was really good! The timeline seems to have stopped working for me however, not sure if it's clashing with another extension or Google/Youtube updated something.

If the timeline bar starts working again I'd change to 5 stars. May try reverting to the last version to see it it fixes, but for now I'll just avoid YouTube shorts lol

All the functions are fine, but it makes scrolling down on youtube shorts really laggy and sluggish. From instant to like 2-3 second lag between tapping the down arrow and the action happening.
