The polish stands out - all the little tweaks makes it look nice and shiny. It is the little details that make a difference. Nice work. 
A big thank you.
What stand out the most is the text and text boxes seem sharper, cleaner. This is on a PC with fonts blown up 150%. Just seems cleaner. Very nice.
Only one tiny little thing I have noticed. Now there are “colo(u)rs” mentioned in the settings it means more languages required. The “user Interface” page lets me select English (UK), and then comically underneath that it show “colors” in USA spelling.
If someone can point me at the USA language file, I’ll attempt to make a properly spelt English (UK) version from it.
