      @brief Convenience tab bar implementation
      This tab bar differs in several ways from the QTabBar:
      - you can close a tab by double-clicking it or through its context menu.
      - it works based on tab identifiers (a fixed id stored in tab data) rather than on tab indices, which might
        change when inserting or removing a tab.
