DisplayFusion will make your dual monitor (or triple monitor or more) experience smooth and painless. With DisplayFusion you can add a taskbar to every monitor that works and looks just like the Windows Taskbar. Or take advantage of advanced multi-monitor wallpaper support, Flickr Integration for image searching and fully customizable window management hotkeys.
