And yet "open mail in new tab" in Gmail has been dead for at least a couple of years now. In fact, I'd say that "open link in new tab" is dead on most of the new web "applications", I'm actually surprised when it works. The same goes for the "go back with backspace" thingie, which Google just killed for no good reason.
Copy-paste is also starting to become a nuisance on lots of websites. sometimes when I try to do it a shitty pop-up shows up with "post this text you've just copied to FB/Twitter" or the app just re-directs me to somewhere else. It reminds me of the Flash-based websites from around 2002-2003, when they were all the rage.
