This extension is one of the best things after uBo, it is just superb, but there is one thing that bothers me, recently a rewatched a video and there was already a sponsor segment marked, but it was wrongly timed, I corrected it, but my marked segment was not saved even though it was the correct one, I think this should be fixed, even though I downvoted the wrong segment, it is the one that still appears in the video.
