Opera Widgets for Desktop

Although they run outside the browser, Opera Widgets have been treated as entities inside the browser in many respects. The new Opera Widgets for Desktop ends this dependency on the browser and moves Opera Widgets to the next level: that of first-class applications. Above all, Opera Widgets for Desktop gives widgets the potential to replace some native applications on the computer.

Opera Widgets for Desktop includes the following features:

Non-modal notification messages

Private browsing

Web Storage

Web SQL Database
