This is a complete fiasco.
Firstly, after the update, I saw a welcome window with music, I was freaking out of surprise, why the hell is the browser yelling with a welcome sound?
Secondly, the appearance is disgusting. Starting with rounded corners in the interface of the browser itself, ending with rounded corners on site pages. Why else is this?
While other programs and browsers strive for minimalism, customizability and a simpler interface - Opera introduces Opera One with tab animations, an inappropriate purple color accent, a broken Speed Dial (no pictures), a grouping of tabs that I did not ask for and which is not can not be turned off and just terrible appearance. Shadows under the tabs, seriously? Are we in 2010? I loved Opera and have been using it since 2007, survived its transition to Chromium, but what is happening with it now is very disappointing.
