request about the title bar icons

[shinlan]

I write this message to suggest that more options are added for the title bar icons, the theme is beautiful, but the icons inherited from breeze are incongruous, could you do something in the style of the classikstyles project? This project allows you to choose other icons in title bar, the drawback is that it does not draw the rounded corners well, unlike Lightly and lightly shaders that make a perfect combination, could you review the other project and think if you can do something similar?https://github.com/paulmcauley/classikstyles
