Feature description

Newpipe should be completely navigable and accessible using Android TV or similar devices. There should be no touchscreen-exclusive actions.

Why do you want this feature?

Plenty of issues opened about TV navigation being problematic. I'm closing them all in favour of a single, easier-to-track issue. This will have to be done during/post rewrite anyway.
