"R2020 will be a series of releases throughout the year, with a focus on quality-of-life improvements. In the first release of the R2020 cycle, we have improved one of the most used and important parts of the web browser – tabs.
 
Tab organization redefined

Many of us know the frustration associated with having a disorganized browser, with simply too many tabs open. We might be neat freaks at home, but we still often end up with numerous open tabs in various windows or even different browsers, in an attempt to keep them organized.

According to a survey we conducted, 66 percent of people in the US use the same browser for work and personal browsing, and 65 percent reported, that they would like to keep their browser better-organized. We also found out, that almost 60 percent would like to group tabs according to the contexts they need them for, e.g. work, shopping, free time activities. Moreover, half of those surveyed stated, that a messy browser has a negative impact on their mood.

Our release today provides a whole array of solutions, that help you stay better organized while you browse.
 
The Workspaces lets you organize tabs according to different contexts you use them in

Right now, you can add up to 5 workspaces, name them, and designate their icons. This allows you to keep tabs: for work, free-time activity, or any other projects in separate tab groups called workspaces.

Workspace icons are quickly accessible at the top of the sidebar, with your active workspace's icon highlighted in blue, allowing you to easily spot it. And if you’d like to open a link in a different workspace, simply right-click it, and send it to the workspace of your choice. You can also move tabs between workspaces, using the tab context menu.

And how do you find a website you opened once, and which has gone missing in a sea of tabs? Simply use the Ctrl+Space shortcut, and type in a keyword.
 
See the tabs you’ve opened twice and remove duplicates

Opera has also added a nice little tool, that highlights duplicated tabs. When you hover your mouse over a tab, those with the same address are highlighted. This allows you to remove redundancy, both simplifying and speeding up your browsing.

 
The new visual tab-cycler

We frequently switch between many open tabs throughout a day of browsing. With Opera, this has just become significantly easier, as we updated the Tab-cycler to be horizontal, and more visually accessible.
You can bring up the Tab-cycler with the Ctrl+Tab shortcut, and use it to switch between tab thumbnails, without lifting your hands from your keyboard.

 
Easily adjust the sidebar to your needs

Another R2020 addition to the Opera browser is setup for the sidebar panel. Clicking the three-dot menu at the bottom of your sidebar, opens up this well-organized panel with a comfortable, and intuitive visual interface for managing elements in your sidebar.

It lets you edit, or remove any of the sidebar elements individually, like messengers, or features like My Flow or Crypto Wallet. It’s also where you can customize Workspaces by adding, removing, editing or hiding them.

Other elements in this setup include Opera's tools – browser management areas, like: History, Bookmarks and Extensions – which can be opened as full-page menus, by hovering over their label, and clicking the link icon.
 
Access useful extensions in the sidebar

The sidebar extensions, that you add to your browser are now readily available and visible from the same sidebar. With this update, we’ve decided to make extensions as accessible and easy to use, as your messengers, bookmarks, history and downloads. With one click, you can access: Twitter, Instagram, Google Translate, or any extension you wish.

When you install a sidebar extension, its icon will now appear at the bottom of your sidebar. Choose which extensions are visible by right-clicking your sidebar, or by selecting them in the setup panel. While there, click the add more button to visit the Opera's add-ons store.
 
Improved security with DNS over HTTPS (DoH)

When someone types a website address, like www.opera.com, the browser has to translate (resolve) it to an IP address, such as 35.158.61.69. This is done through a Domain Name System (DNS) resolver service, one of the oldest surviving parts of the Internet. By today’s standards, DNS is too trusting, as the data exchanged between the browser and the DNS is not encrypted. DoH is a way to make it more robust, by increasing user privacy and security. In simpler terms: it prevents eavesdropping, and manipulation of DNS data from the man-in-the-middle attacks, by using the HTTPS protocol to encrypt the data between the DoH client (Opera browser), and the DoH-based DNS resolver.

Opera now allows you to enable the DoH feature, and choose your DoH server from preselected list, or customize it to any DoH server, by using the browser’s settings.
 
Improved Video pop-out (picture in picture)

Following up on popular requests, we have also enhanced the Video pop-out feature in the browser. When you watch an online video, the pop-out lets you separate it into its own floating window, which stays on top of other windows. This popped-out video is easily resized and controlled, so you can keep it playing in the corner, for example while you browse.

This feature now allows even further control over the video, with added timer, back-to-tab button, as well as next-track button."
