Great addon makes using YT so much better. I have 900+ subscriptions so as you can imagine checking them is really hard but this addon makes it so much easier as you can group channels. Gaming, music, sports, news, tutorials, exploring and asmr is the groups i use.

The only issues I have with it is the way you add channels to the group in the new manager, by drag and drop, It would be nice if you could multi select and then drag them to the desired group as this would be quicker.
