but the text doesn't reflow like in Opera 12.
'Word wrap' works fine here but it depends on the page. If the page uses scaling it will reflow. If it is fixed width then it will not and you will have to scroll left and right to see everything.
That's another reason why I still use 12.17, the fit to width function, I even have it as a right click menu item. Wikipedia is an example of a page that will "reflow"
