Hi, Opera GX team!

I would like to suggest a new feature for the browser that allows users to display two tabs side by side within the same window, without needing to open a new instance of the application. This functionality would be similar to what we find in text editors like VSCode or Sublime Text, where we can split the screen to view and work on two documents simultaneously.

I believe this feature would be extremely useful for users who often need to compare information from different websites or multitask, enhancing productivity and making the browsing experience even more efficient.

Thank you for the great work so far, and I hope you consider this suggestion!
