I agree. Why change a behavior that's been there from the start?
I suspect you are a troll or an idiot. No one said anything about changing the behavior, but about make it OPTIONAL to change it. That's a big difference.
I can probably see adding an option to change the behavior. But again, why?
When almost every week someone appears on Opera forums asking if this can be done what do you do? Tell him to fuck off, or make it an option? Give him that option and you please both camps. I, for one am not using Opera until they make it an option. So there's your answer.
Just to follow some other browsers' behavior?
If that means getting more users... Opera is a commercial product after all.
