I officially give up.
I've been literally trying for two hours now. And I can not get this "Tab Island" Feature to work.
I've re-installed like 3 times. Updated. Tried to install Opera One, since the only documentation on how it's used, is on Opera One Materials.
I really give up. Someone help me? All this conveniently cropped Gifs and Videos everyone only show drag and dropping tabs. Opera One Talks about CTRL Right Clicking multiple Tabs. Nothing works here.
I enabled Early Bird. Yes. My Opera is on "Level 7" whatever. Sorry if I sound pissed, but documentation is a serious Nightmare.
