YouTube New Design and Dark Theme

I can’t tell you guys how much i love the new YouTube feature. They just released a preview of the new Design. You can activate the preview for the Main Pages with this Link.
In the picture you already can see the new Dark Theme Mode. You find it on the top right corner if you click on your Profil and choose Dark Theme. You just have to flip the Switch. If you clicked the Link above every time you open YouTube now it’ll automatically go to the new Design. Unfortunately they didn’t apply the Theme on all areas of Youtube yet. Can’t wait guys!
