Feel the need for two layers of tabs in your browser? Vivaldi has you covered It is very difficult for web browsers to be able to honestly make the claim that they have an exclusive feature these days -- the likes of Chrome, Edge, Firefox et al have started to become all but indistinguishable from one another. Looking to stay ahead of the pack, however, Vivaldi has launched a new feature which is unique. While the likes of Google have been experimenting with tab grouping and pinning to make room for more open tabs in a browser window, the latest version of Vivaldi has taken a new approach. With the new release you have two layers of tabs to play with, doubling your browsing opportunities.
