I'm a Windows user (go on, press the down arrow) and I don't care about app design. Give me military ship grey windows, text menus and a way to hide all icons. Windows 2000 was for me the apogee of 2D design.
To do so:
* Right-click on the Desktop background, Personalize
* Select Window Color button/link at the bottom
* Select "Advanced appearance settings..." link
* Click on the Active Title Bar in the preview area, or
select Active Title Bar from the Item dropdown
* Customize the font appearance, including font, color, size and weight.There you go. Nothing wrong with the comment, but since you asked...
The people mentioning "this is an unpopular opinion", "why the downvotes" or "this will be downvoted to hell" always get the upvotes and indeed, I see the comment doesn't turn gray when I downvote so it means others already upvoted.
