| The UI looks so good. Why can’t we have good looking things anymore? I spent hours each month looking for a way to bring back Aqua on Mac or Linux through theming or alternative DE but nothing comes close to the real thing. If one day I have enough money I’ll just start work on a new DE to faithfully recreate Aqua. One can dream. |
This is also why most "windows style" themes fall flat: you can copy the window decorations, button backgrounds, and icons, but unless your applications are designed to look and work like the OS your mimicking, it'll all just look weird and off.
At this point "operating systems" in a commercial sense are so large that only relatively new entries can afford to rebuild their stock applications to fit the current UI theme (ChromeOS comes pretty close but you'd need to appreciate Google's design to enjoy that). macOS, Windows, and even Linux to some extent all have decades of old software to support so they can't redesign their core GUI stack without breaking everything.
In the days that an internet browser wasn't considered a core part of the operating system, there just weren't as many places to get the design wrong or off-template without Q&A noticing.
