Vivaldi Technologies released the new stable version Vivaldi 3.5 this week and today the latest browser snapshot that highlights new features that will be included in the next stable release of the browser.

Today's browser snapshot 2130.3 improves the web browser's tab stacking functionality. Tab Stacks are an essential part of the web browser and a remake of the tab stacking functionality of the classic Opera web browser.

All it takes is to drag and drop tabs on top of each other to create stacks. These stacks take up a single spot on the tab bar and are ideal for bundling sites together.

Up until now, Vivaldi displays a small bar on top of the stacked tab that users could click on to switch to another tab of the stack. Version 3.5 introduced a visual representation of the stack that displays automatically when the mouse cursor hovers over the tab stack.

The newest snapshot introduces yet another tab-related feature: the option to display a second tab bar that displays when a tab stack is selected.

The feature is not enabled by default, and users need to make two configuration changes in the snapshot to enable it. One of them will likely be removed when the feature lands in the stable version.

  1. Load vivaldi://experiments/ in the browser's address bar.
  2. Locate Two line tab stacks on the page that opens and check the box to enable the feature.
  3. Load vivaldi://settings/tabs/ in the address bar next; this displays Vivaldi's tab management settings.
  4. Scroll down to Tab Stacking.
  5. Switch to "Second row of tabs" to enable the new feature. You may optionally check "use dotted tabs to visualize the stack" if you want.

Create a new tab stack or switch to an existing one afterwards to see the effect of the change. When you select a tab stack, a second row of tabs is displayed automatically; this tab displays all tabs of the stack so that you may select these tabs directly as if they were displayed individually.

Closing Words

The option to display a second tab row for tab stacks is really helpful; users of the browser who use tab stacks regularly may find it useful, even if it means that there is a light visual disruption whenever users switch between tab stacks and regular tabs.

Now You: do you use tab stacks or grouping features?

      Well it is a bit difficulty to distinguish between domains and files for instance.

    The comments section under this very article (3 comments) is identical to the comments section found under the following article:

    Not sure what the issue is, but have seen this issue under some other articles recently but did not report it back then.

    With the cloud, there is no such thing as unlimited storage or privacy. Stop relying on these tech scums. Purchase your own hardware and develop your own solutions.

      This is a certified reddit cringe moment. Hilarious how the article’s author tries to dress it up like it’s anything more than a png for doing the reddit corporation’s moderation work for free (or for bribes from companies and political groups)

    With Google Chrome, it’s only been 1,500 for some time now.

    Anyone who wants to force me in such a way into buying something that I can get elsewhere for free will certainly never see a single dime from my side. I don’t even know how stupid their marketing department is to impose these limits on users instead of offering a valuable product to the paying faction. But they don’t. Even if you pay, you get something that is also available for free elsewhere.

    The algorithm has also become less and less savvy in terms of e.g. English/German translations. It used to be that the bot could sort of sense what you were trying to say and put it into different colloquialisms, which was even fun because it was like, “I know what you’re trying to say here, how about…” Now it’s in parts too stupid to translate the simplest sentences correctly, and the suggestions it makes are at times as moronic as those made by Google Translations.

    If this is a deep-learning AI that learns from users’ translations and the phrases they choose most often – which, by the way, is a valuable, moneys worthwhile contribution of every free user to this project: They invest their time and texts, thereby providing the necessary data for the AI to do the thing as nicely as they brag about it in the first place – alas, the more unprofessional users discovered the translator, the worse the language of this deep-learning bot has become, the greater the aggregate of linguistically illiterate users has become, and the worse the language of this deep-learning bot has become, as it now learns the drivel of every Tom, Dick and Harry out there, which is why I now get their Mickey Mouse language as suggestions: the inane language of people who can barely spell the alphabet, it seems.

    And as a thank you for our time and effort in helping them and their AI learn, they’ve lowered the limit from what was once 5,000 to now 1,500…? A big “fuck off” from here for that! Not a brass farthing from me for this attitude and behaviour, not in a hundred years.
