@elextr Ahh okay thank you. I am aware a little bit about how CSS is used to modify GTK item, this would have been my next approach if this did not work out. Just thought it was odd that the settings offered ability to change the sizes but nothing was occurring. I will first temporarily just try some other themes to see if any contain more sizes just to get an idea but then I will see what gtk.css file can change. Thank You again for verifying this, I will close this.
