I see you decided to take out the option to use the classic tab switching style from the 'flags' page.
I don't expect any response to this message but this made me switch to another browser after using Opera since the first smartphone I ever owned. You have no features that set you apart from other browsers other than being the only one with easy one hand tab switching and you took that out in the name of 'progress'.
I'm honestly very disappointed. I know my (and probably hundreds of other users') opinion won't change your mind, but I just wanted to let you know because I really dislike software devs just removing features because they decided it's better for their users.
Hope I'll be able to switch back to opera someday.
