I recently installed Linux Mint Cinammon on an old laptop to try it out. The Title bar on windows is too tall for me preferences. I poked around in settings but couldn’t find a way to make the title bar shorter. Is this not possible or is there some CLI-fu config to force it?
I’m guessing you mean that it is too thick in which case only 2 things will change this, the theme and the font size, I have for now only found 2 themes with a reasonably sized title bar that aren’t too ugly, adwaita-slim and dracula-slim. If you look for “compact” or “slim” in sites like cinnamon looks you might find ones you like better
the font you had before you changed it may have already been hitting the minimum size of your gtk theme
