Opera includes built-in tabbed browsing, a bookmarks bar, add-ons, and a download manager. Opera has "Speed Dial",
which allows the user to add an unlimited number of pages shown in thumbnail form in a page displayed when a new tab is
opened. Speed Dial allows the user to more easily navigate to the selected web pages.
Opera Software introduced a new release cycle consisting of three "streams" that can be downloaded and installed
independently of each other: Opera developer, Opera beta and the Opera final release. New features are first introduced
in the developer build, then, depending on user feedback, progress to the beta version and eventually to the official
release.
