Post-Annotator: time in "edit annotation" should refer to time of the video
I don't know if this is possible and it might anyway be different as soon as the swimlane is there, but at the moment it's confusing for users that the time/date when you edit an annotation in the post-annotator refers to the timeline and not to the timecode of the video. Some students accidentally moved the annotation out of the time-range of the video, so they disappeared.
