So I did some poking around recently and figured out that I could download other launchers like HALauncher which are much more customizable than Sony's customized version of Leanback. Unfortunately I can't figure out how to set HAL as the default launcher? I vaguely remember reading somewhere (that I now can't find) that Android TV 6+ may have done away with the ability to sideload other launchers? Anyone have any insight into this, and/or suggestions?
