if you at opera software asa don't do anything to bring back the (most of the) features of the 12.x series, you will dig your company's grave, because you lost every user who held on to the opera browser until now.
(i won't switch to another browser now; i will use 12.15 as long as possible.)
it was great while it lasted, good luck on the other side.
i really miss presto. that was a unique piece of art of mankind. but when i learned that you switched to webkit, i was optimistic. i'm still optimistic, but i keep using opera 12 until it becomes really out-of-date, or you implement most of the features that made opera the number one browser. i just hope it won't last years. the mouse gestures are ok, the new speed dial looks promising, but i need an rss reader, customizable buttons, and a fully customizable gui, and basically all the features i've been using since the first time i launched opera in the mid-2000s.
please don't become irrelevant.
it's a pity, very unfortunate, that you haven't further developed the old branch. now opera is just a copy of a lousy browser.
you had completely disappointed me.
i might come back someday when you have re-implemented the missing features. others might not.
