Two-level Tab Stacks – Vivaldi Browser snapshot 2130.3

Today’s snapshot includes our new Two-Level Tab Stacks, even more configurable menu options, and lots of regression fixes.

Two-level Tab Stacks

We have been doing quite a lot of work on tabs behind the scenes. You saw a glimpse of this in 3.5 stable, with the improved Tab Stack tool-tips. But that was just a taster! Today we introduce Two-Level Tab Stacks. Unlike the old compact view, each tab within the stack is now full size. This is achieved by creating a second level to the tab bar, that appears when you click on the stack, and works whether you have your tabs on the top, side or bottom.

This second level makes reorganizing stacks or creating new tabs within a stack vastly easier, and gives you all the other benefits of normal sized tabs, like easier to read page titles, page title tab notifications, and (if you enable them) tab thumbnails.

In addition, you can lock the second level, which avoids changing the page view height when switching between tabs, and makes it simpler to create new stacks from any single tab (they each then get their own dedicated + button).

However, if you still prefer the old compact view, no problem! We didn’t take it away, its still there in settings. 😉

Note: Two-level Tab Stacks are currently behind an experiment flag but they are ready to test, just enable them in: vivaldi://experiments
