I was watching a video on Youtube the other day and had to stop watching before the video was done. I closed the browser without pausing the video. When I navigated to the same video it picked up where I left off watching. That was cool enough, but there were additional delights.
The play bar had a few new interface controls that appeared when hovering near the play bar...
The video resumed playback at the exact time code of when I stopped watching,
and just in case I did not want to resume at that time when the mouse hovered near the bracket an X was available with a label "Watch entire video."
If the X was clicked the video would start from the beginning!
Well done!
