" Im working on tool that allows create leanback channels from youtube channels...This version is preview, not production ready, proof of concept etc ;)You can play with it it, but i can't guarantee that it will work properly.
Features:- Search for channels by name- Search for channels by id- Add channel to leanback- Open video in official youtube app- Open channel in official youtube app (if you select channel icon at left)- Ignore video clips- Background updates"
Edit " the dev has made beta access open now

I've been using this app for weeks now and it's fantastic. The creator keeps adding features and fixing bugs.
Latest update allows now to select the app you want the youtube video to open in. Which is awesome if you primarily use Smart YouTube TV instead of the built-in YouTube app.
