No, it's not a workspace, I always disable the workspace because I don't need to use it, I'm pretty sure it's the tabs feature, when you right-click on one tab, and you already have many tabs opened from the same site, it will show in the right menu options to move all tabs related to that site to a separate tab bar below the main tab bar, sorry I removed Vivaldi, so I can't determine the exact name of the option, but the end result will be as shown in the image below.I think it's Workspace. It was here, but I ended up removing it. If you want it, you have to customize it using the toolbar, but thanks for the tip. Thank you very much, and you too, @Parkinsond, from the bottom of my heart. I know about Chrome, but unlike Vivaldi, it doesn't offer much customization.![]()

Note that the second tab bar contains tabs related to the same site, this helps me when I have for example many MT tabs open and start searching for answers to questions asked by members and the tabs get confusing, this feature will help me separate the MT tabs on a second tab bar and continue searching in the main tab bar which makes me manage tasks better.
