How to scale menu, titlebar and window buttons?

[Zorunimac]

I didn't say that I prefer Unity!

If there is no implementet feature in the GUI to adjust this, then maybe this topic should be moved to the customization category?

I also found this topic

Windows titlebar icons - changing size/scale?

Well, I am a themer, so this is something I know a little bit about: https://www.deviantart.com/aravisian The icons within the button.image are set by the Icon Theme not by the Button size. This is something we can change, too. Let's try setting the system theme up to be a certain size, then set the Icon theme up in similar fashion. .nautilus-window entry, .titlebar entry, window.ssd headerbar.titlebar, .titlebar, .titlebar button *, headerbar button.titlebutton * { min-height: 42px…

There they adjust the theme files. The intention is not the same like mine, in that topic they want to make it bigger. But is that the direction I should take?
Thanks for the help!
