This is a web browser.
Things that you can change include how it looks, skins, remove icons, and download add-ons, and so on. No other browser is known to let you fiddle with so many things inside it. The two different rendering engines to choose from do not slow down anything. In fact, the browser is quite fast. It is multi-tabbed like most modern browsers are anyway. The browser is designed to consume very little of system resources. Special plug-ins and the add-ins to the IE will make your browsing experience very enjoyable. Some of the other useful features include Drag & Drop, auto scroll, mouse gestures, form auto filling, Ad hunter, plug-ins support, online favorites, external tools, customizable skins, and an auto-hide panel. This is a remarkable product. If you have the need, just go ahead and use it. In fact, give it a try even if you have no compelling need.
