I installed SmartTube on the TV and oh boy is this software great! I did it to get SponsorBlock (I'm already paying YouTube premium to get rid of ads), but that is by far not the only feature I love about it.
- flexible time hiding the UI of a video (have it to 1 sec now)
- not showing UI when pausing
- way faster scrolling
- instant loading
- way faster account switching
- instant voice search
But there is one feature missing, changing the search language. We speak combined 7 languages at home and it's impossible to search anything other than in english which is really annoying.
