Do you miss the days when it felt like Opera was focused more on avid web surfers than the broader public? So does Opera's former CEO Jon von Tetzchner. He just released the finished version of Vivaldi, a web browser that caters primarily to power users that thrive on customization and shortcuts. It has Opera mainstays like Speed Dial (quick access to favorite sites from new tabs), but it also has tab stacks, mouse gestures, annotation, browser sessions and even the option to view websites in a sidebar. In short, it's all about removing clutter and speeding things up. Vivaldi even supports Chrome extensions (it's based on Chromium), so you shouldn't have to scrounge for replacement add-ons.
