Nuked Vivaldi first introduced the feature as an experiment in December 2020. Now you can create two-level tab stacks, so that grouped tabs can become pseudo-workspaces for whatever you get up to in your browser.
Clicking on the newly formed tab stack reveals the second row of tabs nestled inside. Tab stacks can be renamed and closed all at once from the right-click drop down menu.
With the two-level tab stack, each grouping can function as a visually distinct workspace. It could be a way to silo distracting tabs in your window while preventing you from losing a page when you really need it.
Vivaldi also lets you put tabs on the sides and the bottom of the browser window. The new two-level tab feature works in those orientations, too.
Vivaldi’s Chromium-based browser has been geared towards power users since its inception. It’s highly customizable, full of features, and seemingly pretty great when it comes to privacy.
