As promised, the 5231 version of Internet Explorer will include revised features that users can see right away, rather than dig beneath the surface to locate. A new "Favorites Center" will apparently improve the way bookmarked and previously visited addresses are displayed in the sidebar, as well as subscribed RSS feeds. In an attempt to "one-up" Firefox, not only can open pages be displayed in tabs, but tabs can be grouped together, and the resulting group can be saved as a bookmark or tab in its own right, to be launched all at once. The contents of tabbed pages can be shown as thumbnails, probably down the left side of the sidebar or top side of the workspace, according to user preference, if early peeks at this feature were accurate.
Other features in the new IE build include an advanced "Phishing Filter," which may operate in conjunction with an anti-phishing service that Microsoft has planned.
