What are some features you would like to see in Windows / Old features to report to the operating system | Promotion Forum

As the title says, what new features would you like to see in Windows, or are there old or deleted features you'd like to see come back?

Personally, I would like to see the Aero Glass theme or the added classic theme. It's not that I hate the new Fluent design but I prefer much older designs like Apple's Skeuomorphic IOS design.
