Yes, this is Youtube's new "One Channel" look.
The option for me popped up yesterday, previously it had only been available to a select few big name Youtubers as a trial.
https://www.youtube.com/onechannelI enabled it, and I think it does work look and work pretty well.
Although I have yet to optimise it and do graphics for it properly, I just bunged up what I had available.
I like the "Promo video" option that gets auto displayed to people who are not subscribed. So they will automatically see a promo video you select in order to entice them to subscribe to your channel. I put up my old existing one I did for a contest. It's ok, but I need a better one.
Any suggestions are welcome.
Dave.
