"Classic" is 100 times MORE EFFICIENT and allows us to use normal interaction with a web page and not be forced into someone's "fancy" concoction !Q

And clean up the new interface to that Right-click on e-mail itel let's us use normal "open in new tab" - BROWSER TAB - the one that we can normally pull out into a windows and do whatever we want to do with it.

I don't want to see your own concoction a'la "our own, inner tabs" - ever ! Doesn't serve any real purpose, bloats one and the sane real tab and doesn't allow real separation => doesn't allow really working on 5 or 10 e-mails/threads and having clear view of everything (on larger monitor).
