Presently, it seems that whenever you finish a video it randomly chooses another when on auto play to go to rather than playing the next episode in the series you are watching.  It would be nice that if you are watching a series, for example Hardcore Tabletop, that upon completing the first episode it would go to the second episode rather than anything else.  Alternatively, at least having that season of the series listed below so that you could at least click that instead of needing to travel back to the series page in order to choose the next episode to watch.
