Opera 11 has been released, offering extensions, tab stacking, speed improvements, and many other new innovative features like tab stacking.
Dragging one tab over another allows you to create groups of tabs. Now you can keep dozens of webpages open, organized and under control. This is called Tab stacking. Tab stacking is a better way to organize your open tabs. Simply drag one tab on top of another to create a stack. Also, when you open pages as background tabs from another pages, Opera will automatically create a stack.
With the flick of your wrist, mouse gestures let you navigate back and forwards, open new pages, close tabs and so much more. In Opera 11, you now have a handy visual guide to the wonders of mouse gestures.
Opera 11 also has a changed the address bar, so you can make better sense of the security levels of the sites you visit. Opera 11 now displays a clear badge indicating the security level and allowing immediate, one-click access to security and trust information about the site.
New Extensions have also been introduced. Opera Link, Opera Turbo and Opera Sync continue to remain!
