Windows also need this for 10 years, since Windows 10 launch. But never happened. I guess it's just not really viable, as they need to continue selling new devices...
I still don't understand how there can be like 10 different UI styles in Windows 11 with no progress to getting that fixed. It feels more likey they are adding new ones instead...
They should go back to the Windows 2000 theme, that was the best one.
They should go back to the Windows Vista theme, that was the best one. Liquid Glass proved it.
WinUI looks good for me. Improvements on efficiency are needed before it can become mainstream though.
