Opera One, is Opera's new commitment to a modern web browser
Opera does not stop putting its finger on the table in relation to the competition of web browsers, although it is more than clear that it is far from having a user market that can even come close to that of Chrome or the most popular web browser at the time.
This situation has been the same as always, (at least since I can remember since I got into this Linux thing). But something that Opera should be applauded for is that despite this the situation has not discouraged it and it has always had quite good innovations for users.
The reason for mentioning this is that it recently became known that Opera has started testing its new "Opera One web browser", which, after stabilization, will replace the current Opera browser.
About Opera One
OperaOne continues to use the Chromium engine and features a modular architecture completely redesigned, multi-threaded rendering and new tab grouping capabilities.
The way browsers handle more complex tasks has changed a lot in recent years, making them more efficient and improving their performance. The same can't be said for the browser's user interface, though, which hasn't kept up. This is due to the inefficient way the browser's user interface reaches your screen, so we decided to change that, by introducing Multithreaded Composer in Opera One.
The transition to a multi-threaded rendering engine has significantly increased the responsiveness of the interface and the efficiency of using visual effects and animations. For the interface, a separate thread is proposed that performs tasks related to drawing and displaying animations.
A separate rendering thread offloads the main thread responsible for rendering the interface, which allows for smoother rendering and prevents hangs due to blocking on the main thread.
You may already be using Opera One, the latest evolution of the Opera browser. If so, one of the changes you may have noticed is the revamped user interface with new features like Tab Islands and buttery-smooth, fast animations.
To simplify navigation through a large number of open pages, the concept of “Tab Islands” is proposed, that allows you to automatically group similar pages according to the browsing context (work, shopping, entertainment, travel, etc.). The user can quickly switch between different groups and collapse islands of tabs to free up panel space for other tasks. Each tab island can have its own window color scheme.
In the renderer part of a Chromium-based browser, there is a main thread and a compositor thread. The main thread is responsible for coordinating and managing the overall rendering process within a browser. It interprets HTML, CSS, and JavaScript code, creates all the states of a web page, handles user input such as clicks and scrolling, and communicates with the composer thread to help update what is displayed on the screen.
The composer thread is responsible for taking the elements that the main thread produces, so that they are displayed on the screen. This includes effects like animations and transitions.
In addition to this, it is also highlighted that the sidebar, through which you can manage workspaces, has been modernized with groups of tabs, placing buttons to access multimedia services (Spotify, Apple Music, Deezer, Tidal) and instant messaging (Facebook Messenger, WhatsApp, Telegram).
Furthermore, the modular architecture allows additional features to be integrated into the browser, such as interactive assistants based on machine learning services such as ChatGPT and ChatSonic, which can also be integrated into the sidebar.
Finally for those interested, they should know that the Opera One compilations are already offered and They are prepared for Linux (deb, rpm, snap), Windows and MacOS.
I don't know if it's going to beat Vivaldi, but it's an interesting proposal, he works by giving his best
