Some of the adjustments you can make to your Vivaldi Theme are more subtle than others. One such customization option is removing the faint background from the tabs you have open in the background.
To make background tabs transparent:
Notice something interesting while browsing or remember something you need to get on next, but want to finish checking out the current web page first? Opening links in new background tabs is just what you need.
To open links in the background:
You know you have a lot of open tabs in Vivaldi on iOS, when instead of a number on the Tab Switcher button you see :D. To keep the number of open tabs manageable, clear the unused ones regularly.
To close all inactive tabs:
By default, a tab will be set to inactive if you haven’t used it in the last 21 days, but you can select the interval for when a tab should be moved to Inactive from Settings > Tabs > Inactive Tabs.
You can find Keyboard Shortcuts for numerous actions in your Vivaldi browser and with Command Chains you can make many more. For example, you can create a chain for moving the active tab to a different Workspace and bind it to a Keyboard Shortcut and Mouse Gesture of your choice. You can also type the chain’s name in Quick Commands and even add a custom button on one of the toolbars to execute the chain on click.
To create a command chain for moving the active tab to a different workspace:
“Add Command Chain”. “Add Command” button in the top right corner of the first command to add the next one.
New Gesture and find the chain you created.It’s easy to end up with more open tabs than you can keep track of. That’s why, when you type a link in the Address Field, Vivaldi will point out that you already have the same URL open in another tab, allowing you to switch to that tab instead of opening a duplicate tab.
To switch to an open tab:
When you feel like the browser is getting a little sluggish, it’s likely that one or more of the tabs is using a lot of resources. In that case, it might be a good idea to close or at least hibernate the tab(s). To find the resource hogs, simply hover over a tab on the Tab Bar to view their memory usage.
If you don’t see Tab Thumbnails on hover, go to Settings > Tabs > Tab Display > Tab Options and make sure “Show Popup Thumbnails” has been enabled.
Web Panels are great for taking a quick glance at a website, but occasionally the mobile-sized view may not be enough. In that case, you can open the current page you have open in the Web Panel in a tab instead.
To open a Web Panel in a tab:
If adding a search widget to your Home Screen on iOS (see Tip #389) is not to your liking, you can still open Vivaldi with a new tab ready to type in a search keyword or a web address.
To open a new tab with focus on the Address Field:
Vivaldi keeps the most recent tabs, you either unintentionally closed or have changed your mind about closing, available in a list, from where you can easily reopen them.
To open a recently closed tab in the active tab:
Vivaldi menu and select 
“Recent tabs”.To open a recently closed tab in a new tab:
Closed Tabs tab.
If you have “Switch Tabs By Scrolling” enabled in Settings (see Tip #184), you can switch tabs by using the scroll wheel on your mouse. But did you know, that you can also switch Workspaces like that?
To switch Workspaces:
Grouping tabs into Tab Stacks is an excellent way to keep your tabs well-organized. If you want to turn multiple stacks into one, you can do that using drag-and-drop on the Tab Bar or Windows Panel.
To merge Tab Stacks:
If drag-and-drop doesn’t seem to work, go to Settings > Tabs > Tab Features > Tab Stack Options and make sure “Allow Stacking by Drag and Drop” is enabled.
Have you cumulated a set of tabs that you would now like to move to a new workspace? Instead of first creating a new workspace and then moving the tabs, you can also create a new space while you moving tabs.
To create a new workspace from open tabs:
Reduce memory usage by automatically hibernating tabs that haven’t been used in a while. This way, active tabs, such as those used for gaming or streaming, can run more smoothly.
To enable the Memory Saver:
Cycling through tabs using Keyboard Shortcuts or the scroll wheel of your mouse while holding down the right mouse button is a convenient way to switch tabs. In Vivaldi, you have the power to choose in which order the tabs are cycled through.
To make your choice:
Bonus! See how to enable the visual Tab Cycler in Tip #267.
