Brave’s sidebar feature is useful for providing quick access to frequently used websites. However, currently, when clicking on a site, it only opens as a new tab, which limits its flexibility.
Therefore, introducing a solution similar to Opera would be a great improvement: When a site is clicked from the sidebar, it could open as a floating window (dockable window) on the right side of the browser. This window would function independently of the main tabs but remain within the same browser interface.
