I'll add $0.01....but that's because I don't like to resize the preview pane...I just double click on the tab to get a large screen view. I don't do ANY editing in BV. I would, however, be willing to give $0.02 if we could double click the preview pane to toggle between maxed and docked....
edit: Oh wouldn't you know it....somebody already went and added that functionality without me noticing....
