The new web browser, which is aimed at power users, includes tab stacks, Opera-like Speed Dial which supports multiple folders, as well as a note-taking feature which allows including a screenshot of the current page. Furthermore, Vivaldi features a tool called Quick Commands, that can be used to search through settings, history, open tabs, bookmarks and more with a single keyboard shortcut.

Vivaldi is also pretty customizable - for instance you can disable tab stacking, change the tab cycling order and place the tab bar at the top, left or right side or bottom and even disable it completely and rely on keyboard navigation only.
