I cannot believe I wake up and not only did opera 1 restart my PC but updated itself to the most hideous UI that has ever been forced upon me in my 32 years of using computers. You have completely wrecked the UI - all my tabs look ugly and are a complete mess. And because of this absolutely incompetent decision - made needlessly as there was never at any point and time a desire by the community for a UI redesign, the tabs convey no information at all. It is a bunch of tiny graphical icons the kind even a little kid wouldnt find appealing. I don't want you AI stuff - never did and no one else did either, but oh look you installed it anyway.
This is one of the worst UI redesigns I have ever seen in my entire life and I thought I had seen them all. Clearly your programmers and designers had nothing to justify their jobs so you allowed this to happen under the veneer of an update, but it is a giant step backwards, the kind of thing you see in a beta release of a product before anyone knows what their identity is. This is terrible and if there isnt an option to undo this I am going elsewhere and I will scream from the mountain tops for everyone else to join me too.
