System requirements and theme addition

Hi, suggestion:

1 - If possible, have the full Windows 7 Pro Aero theme
Working well with a dark theme, on OLED screens, etc., but without losing the characteristic aero theme.

2 - If possible, reduce the consumption of PC resources.
Keeping what is already in KDE, such as effects, etc., just requiring less PC resources.
To leave even more resources for heavier tasks/software.
I don’t know if kde plasma manages swap, but I also wanted to suggest better swap management, when the operating system needs to use it.

intel i3 1115G4

Thank you very much in advance.
