Youtube for the Mi Box seems so needlessly stripped of features. Android TV supports bluetooth and other wireless keyboards and mice and there's plenty of screen real estate and to include the things I mentioned.
The other thing that bothers me is that my subscription list is incomplete. I subscribe to 100+ channcels and at max I am able to scroll through a number significantly smaller than that. Finally, I can't seem to figure out a way to disable autoplay functionality which is always in effect at the end of any video I play.
*I'm only asking this at all because I'm unclear if all Android TV devices run precisely the same build of Youtube with identical UI presentation.
YouTube comments are most definitely not a "feature" and I am happy to not have them on Android TV.
