Currently, autoplay is deeper available to set in Settings>View.
In practical usage, I tweak many times the autoplay settings, and it would be really handy if it is easier accessible in somewhere as a button in the player bar, as showed in this suggestion snapshot:

The autoplay in Settings>View could be kept, and the suggestion of a button in the player bar could work parallel to it.
If you need further info, please let me know.
Many thanks for considering it,
Carlos
