Z80xxc! writes "Microsoft recently announced a new product called Expression Web SuperPreview, which lets developers view their web pages in any browser installed on their system, as well as in different versions of IE, all from the same interface. The product has one genuine innovation — a built-in tool for overlaying the rendering from one browser over another to compare (referred to as 'onion skins'). There are also HTML debugging aids and other helpful tools for web developers. A beta version is available for download. However, the current build only has support for IE — it will compare rendering in IE6 with either IE7 or IE8, whichever is installed. An internal build shows Firefox and Safari on Windows as well. The final product will appear as part of MS Expression Web Studio 3 when it is released later this year. (It will not be available in the Expression Mac suite.)"
