Just bought a Mi Box 3 S. I was wondering if there was a way to add other applications to the Customize Channels (the quick menu on the left side).
I'm only limited to the default apps which are Google Play Movies, Netflix, Spotify, Red Bull TV, YouTube.
there is. it is made by the same guy behind another helpful leanback app. he only asks 99 cents for it. this is the only one i've ever seen.
