I am currently using it on a spare apple device, airplayed to my apple tv, with the iphone screen off, video playing in background, and auto play of next videos. idk... seems like perfection to me.
I also appreciate this project because it's so cool that you had this idea and then executed on it. I have the ability to execute but I just don't have the ability to think of ideas :D. I def want to try and create something similar to this!
One suggestion would be to add another tool on the site that output's a channel's id when a user supplies a youtube channel's URL or just accept URLs in your channel id field and do the all the lookup of the channel ID in the backend. I know there are easy ways to do it while on the desktop. I wasn't able to quickly find a way to do it on the phone. Quickest way I found was to use a 3rd party site where I supply the URL and it outputs information about a channel including it's channel id. I am using iphone.
