Adds a button to toggle a dark youtube style.
Thank you, and yes, it's not all that noticeable. I always intended for the script to stay out of the way, and the button used to be more noticable (a blue circle in the corner instead) but it got in the way sometimes.
In recent versions I have expanded to include a button in settings and in the website footer, though.
Works Fine, Just Hidden. (Looks cool too)
I checked the other reviews and just like the author said, the button is hidden. Bottom Right there is a tiny vertical rectangle that's transparent. If you hover your mouse over it it pops out and looks like the screenshot on the info page. To Author: You should make it more obvious/eye-catching.
