In MacOS app, I have a window created in storyboard, with toolbar style Unified. When launched, the window looks like this:

I need the window title ("General") to have more left padding, in order to be aligned with "Actions" in the window content. How to achieve that?

In the end, I have created a custom NSToolbarItem, that is just text styled the same way as usual window title, but is positioned with required padding

class ToolbarLabelView : NSView {  
    var label: NSTextField!  
      
    public override init(frame frameRect: NSRect) {  
        super.init(frame: frameRect)  
  
        self.label = NSTextField(labelWithString: "MyLabel")  
        self.label.translatesAutoresizingMaskIntoConstraints = false  
        self.addSubview(self.label)  
          
        self.label.font = NSFont.systemFont(ofSize: 15, weight: .semibold)  
          
        NSLayoutConstraint.activate(\[  
            self.widthAnchor.constraint(equalToConstant: 200),  
  
            self.label.leadingAnchor.constraint(equalTo: self.leadingAnchor, constant: 105),  
            self.label.centerYAnchor.constraint(equalTo: self.centerYAnchor)  
        \])  
    }  
      
    required init?(coder: NSCoder) {  
        super.init(coder: coder)  
    }  
      
    public func SetLabelText(\_ str: String) {  
        self.label.stringValue = str  
    }  
}  
  
class LabelToolbarItem: NSToolbarItem {  
     
    override init(itemIdentifier: NSToolbarItem.Identifier) {  
        super.init(itemIdentifier: itemIdentifier)  
          
        self.view = ToolbarLabelView()  
        self.view?.translatesAutoresizingMaskIntoConstraints = false  
    }  
}

If then I hide standard window title like this window?.titleVisibility = .hidden, only the custom toolbar item is there and it looks like window title. It looks as it should, even though it is not very clean solution.
