Youtube has a new look again, actually the Youtube channels are quite different.
Overall impression:setting new channel  is not so user-friendly, but after a while you get used to it.

NEW CHANNEL LOOK

OLD CHANNEL LOOK

Channel ART (header image) has to be at least 2120 x 1192px (!!!) in order to be responsive(?).

But I think they overdid it – Could be better solution for design version for TV.

But it is supposed to look like this on  different screens:

I like the  loader on top of the page -subtle red line, it’s hard to printscreen.

I also like  WHAT TO WATCH   menu with SOCIAL connection apps that give you possibility to view all shared videos cross your

g+, Fb, and Tw platforms.
