To expand or collapse all folders in the folder tree in one go:
/ 
arrow in front of the folder name to expand or collapse the main folder and all its subfolders.Periodic Reloading of Tabs can be used on sites where the page is often updated, but the new content isn’t automatically displayed. That way you can always be up tp date without needing to take extra steps.
To reload a tab every few minutes:
You can see the countdown until the next reload on the Tab, below the page’s favicon and title.
PS! Periodic reloading works on Web Panels too! 🙌
Whether the text on the phone screen is too small for you to read or the opposite, your eyesight is great and you want to fit more text on the screen, Vivaldi for Android has a text scaling setting for you to make use of.

Let’s say you want to get a tree-style view of your open tabs. All you need to do is open the Window Panel. Click on the 
Window Panel icon on the Panels bar and you will have a tree-style view of all your open tabs on one side of your browser window.
From the Window Panel, you can, for example, drag tabs to change their order. You can create a Tab Stack by dragging and dropping one tab over another. Also, you can even tile Tab Stacks to view them side-by-side by right-clicking the Tab Stack and select Tile from the context menu.
When you have so many tabs open that you can no longer see their titles on the Tab Bar, you can use the Window Panel to review and close the ones you no longer need. Just hover over the tab and click on the 
Close button on the right side.
If you want to hide the Tab Bar, the Window Panel is a good way to manage your tabs.

Selecting text on a web page and creating a note from it is an excellent feature in Vivaldi, but what if you want to add new lines from a web page to a note you have made in the past?

3 dot menu to show additional options and select Append to Note.
Done in the top right corner.
Vivaldia is a real 80s style arcade game built into the Vivaldi Browser. There for you whenever you want to take a break and enjoy a quick gaming session.
The game is available both on Vivaldi on desktop and Android and can be played even when you’re not connected to the internet.
To play the game, enter vivaldi://game in the browser’s Address Field. Press Space (on desktop) or tap the screen (on Android) to start the game.
For more detailed instructions about the gameplay, check the Help pages about Vivaldia on desktop and Vivaldia on Android.
Status Bar on the bottom edge of the browser window includes useful information and is the place to access many of Vivaldi’s key features. But sometimes being able to see those extra pixels on a page is more valuable. Or maybe you just like a clean minimalistic look. Hiding the Status Bar would be one way to achieve these goals.
To hide the Status Bar or display it again, use one of the following options:
Vivaldi Menu > View > Show Status Bar.To still use the features on the Status Bar, consider moving the buttons you need to the Address Bar. Check out Tip #102 or the Help page about Editing Toolbars for instructions. Alternatively, look for other ways to access them, for example via the main Vivaldi menu or through shortcuts.
To see which pages you’ve recently visited in the active tab, right-click or long-click on 
History Back and Forward buttons on the Address Bar. Click on the entry in the list to navigate to the page again.
If you want to stay on the current page, but also want to open a page from History, hold down the Shift key while clicking on an entry to open the link in a new tab. Hold down the Ctrl / Cmd key and click or click with you middle mouse button, if you want to open the link in a new background tab.

By default, opening and closing Panels will resize the web page to make space for the panel. But panels can also be made to float over the page content. Floating panels are useful when you briefly want to check something and don’t need to keep it open while working on the page. For example, Reading List Panel could be floating, since you’d only want to quickly add or open a web page from it, but then it should get out of the way again. While the Mail Panel with all the folders is useful to keep open on the side, without it covering anything.
To make all panels float:
Alternatively, Shift + click on the 
Panel toggle button on the left side of the Status Bar.
To change the floating state only for specific panels:
