I still use Opera 12 because of the lack of features in the new version. My biggest pet peevs: Ctrl+Tab behavior (Opera default was 'previous tab' now it's 'next tab') and no thumbnails tabs on the left, and they removed the email client.

While it's lacking the menu, there is at least opera://flags/#activation-order-tab-cycling now.

Yeah, I dislike both of those changes as well. I have a pretty long list of things Opera needs to add to versions beyond 12 before I will update to their Blink version. Until then, I'm still using 12 as well.

I'm also sticking to Opera 12, missing quite a lot of features in the Blink version...

And the IRC client and BitTorrent client?
