For me, this is step backwards, because it breaks existing UI paradigms.<p>Why is it a good thing for the preferences pane have to appear in a different place from where it does in <i>every single other application on my OS</i>?<p>And this deliberately confuses application content versus Internet content. Do you have to scroll down to click "OK"? What if it isn't visible? Or should it be labelled "save"? Why learn a new dialog-style interface? And why on Earth does this need to be a tab -- are people going to be tabbing between their stock quotes, news, and browser Preferences tab?
