As with the old version, you can scroll through videos while the video you are now playing is in the bottom right hand corner. With playlist you now have the option bar of whether to share a playlist or do other hinge with it. However, when you move down the playlist this bar disappears

You can now have the option to move back one video in a playlist an forwards with the buttons next the the annoying pause button in the middle of the screen. This is an improvement on the arrows that were on either side of the screen on the old version which you usually pressed accidentally.

Also, the options bar (share, add to playlist, add to watch later etc) is now on the interface of the video (top right corner) which is a shame as it worked well on the bottom of the comments section however this is but a minor change and has no genuine impact
