Super Web Browser allows you to open multiple windows on the same screen. The screen layout can be changed quickly via quick tab bar buttons. For example, you can watch HTML5 web video ( YouTube, CBS, etc), and use the gmail web app at the same time. Windows are cached in memory so when you switch web sites you don't have to wait for loading. A pop over menu allows you to quickly select bookmarks or already loaded web sites.
