PeerTube's playlists already allow you to list just one clip of a video (and not the whole video), but they did not allow you to include several clips of one video in the same playlist. It is now possible and really simple: go on the page of the video, click on the <i>Save</i> button under the video, tick a playlist and then click on the <em>+</em> icon next to the playlist name. An additional field will allow you to enter different <i>time-codes</i> you wish to add. Playlists can be very useful remix tools, e.g. for educational purposes.
