I'm sorry @Pesala, I didn't mean to insult anyone with my previous comment. Please accept my sincere apologies for any offense taken. My aim was simply to clarify the specifics of the feature request, as I've noticed similar feature requests are often met with suggestions to use the existing "tab tiles" functionality, which doesn't fully meet the requirement outlined.
The essence of the feature request lies in the need for a more dynamic and user-friendly approach to viewing 2 tabs simultaneously. For instance, when researching a topic with 20 open tabs, one might want to keep one tab (let's call it Tab 1) constantly open for comparison with each one of the other 19 tabs, one at a time. The current "tab tiling" feature allows for side-by-side viewing, but when switching from Tab 2 to Tab 3, Tab 1 disappears, necessitating a cumbersome process of re-tiling Tab 1 with Tab 3, and so on for each subsequent tab. This process is not only time-consuming but also disrupts the flow of tab comparison and research.
The proposed feature aims to address this by allowing one part of the screen to be "pinned" with a tab that remains constant (pinning in an wasy way, not a in cumbersom way like pinning content to the side-panel)), while the other part of the screen is used for seamlessly switching between other tabs, where all the browsing occurs. This approach would significantly enhance the user experience, particularly for tasks where the user needs to compare one tab to many other tabs, or view a recipe or a guide in one tab to one side of Vivaldi, and research the web in the other side of the browser. It's about creating a more seamless, intuitive, and efficient way to navigate, compare and research content within the browser, which could be a standout feature for Vivaldi.
This is different from web-panel, as web-panels are more like Vivaldi's "Browser Config", where a user can configure his Vivaldi to have favorite persistant web-apps such as WhatsApp, messages, translation app, notes, etc., that are part of how the browser looks, and not related to the topic the user is browsing or researching.
Again, I appreciate the current features Vivaldi offers and the responsiveness of the community and moderators. This discussion is aimed at further improving the user experience and making Vivaldi an even more versatile tool for web navigation and research. Thank you for considering this request and for your ongoing support and dedication to the Vivaldi community.
