Add a separator between tabs islands

I understand that while we can currently group tabs, I'm seeking a way to visually separate tabs within a group by adding a horizontal line between them. For instance, if I have 10 open tabs in one group and I've viewed the first 6, I'd appreciate a vertical line between the viewed and unviewed tabs to enhance clarity.

Presently, I resort to creating an empty tab and positioning it between the tabs. However, each time I exit Opera, the program automatically closes my empty tab. It would be convenient if we could open a separator by right-clicking on the top of the tabs, as depicted in the attached screenshots.

Additionally, I was hoping that Opera wouldn't automatically close empty tabs, as sometimes we leave them for a specific reason.

Thank you for considering these suggestions.!
