Yesterday, June 6, the YouTube service finally added previously announced functions to its player. This is the ability to view the video from any place (just drag the slider to the desired segment and download starts from it) and display related video in the player window from the beginning of the download (to do this, move the cursor to the bottom of the player window).
For those who do not like innovations, there is an opportunity to turn off the function of displaying videos related to what is being viewed. For this, it suffices to add rel = 0 at the end of the link.
