When you watch videos in websites and in Google Reader and would rather watch it in YouTube site, you have to double click the video to see them separately. But when you double click the video, you have to watch it from the start or wait until it loads. This was annoying since we might have watched a part of it already and we are forced to watch it in the beginning, but now YouTube starts the video where you left off from the previous site.

I noticed this last month but didn't hear any announcement from Google, also it worked on some videos but other videos it didn't. But now the video looks more consistent and you see a smooth transition from the site you watched it first to the YouTube site.

You can try it by double clicking the video after you watch it for some time.

Another feature added by YouTube is when you click once on the video, it pauses and if you want to watch the video the whole screen just double click it.
