I would like to increase the height of the titlebars on windows. I am trying to make my computer look like a Mac and to do so I would like to be able to increase the height of the titlebars (see attached pictures to see why). Is there any way I can do that?

Could you please use an image sharing site that doesn't come with a fat red warning, e.g. imgur?

I didn't realize that tinyupload gave a big red warning.

I uploaded the pics to OneDrive: https://1drv.ms/u/s!AoQta3yJKVfJhBUMh-No5sSoVaV8?e=fdeQYN

IIRC the title bar increases its height depending on the buttons in it, so if you use large or very large buttons this should just work, no?
System Settings -> Appearance > Application Style -> Windows Decorations

Well, that sounds reasonable but I can't figure out how to make the buttons larger or smaller.

Did you even look at the themes? There is a pen icon at the bottom right of each, click on it...

Oops, not sure why I didn't see that before. However, what I would really like to do is change the height of the titlebars independent of the window button size. Is there any way to do that?

very likely, but I guess that would mean dabbling with code or at least make a new theme. Not my turf, but there is plenty of instructions out there, check for the Kvantum theme manager.

I will do that. Thanks!
