Excellent add-on! It's really a must have, specially given the current business model of Youtube. Nowadays it is more common to subscribe to not only the channels you want alerts from, but every single "content creator" you enjoy. Following 900+ channels is not a weird thing anymore, and this extension helps to not miss any video from the smaller channels you love. No algorithm can 100% accurately predict when I want to have scientific mini-documentaries or when I just want to see trashy cartoons. PocketTube comes to fix that need.
