Change only the color of the title bar and window borders depending on the theme.

**Describe the enhancement or feature you'd like**
Hi! I just wanted to suggest that it would be great to add an option to be able to change only the color of the title bar and window borders, without changing the windows accent color and according to the system theme.

For example, having the title bar and window edges completely black in dark mode (which Windows does not allow) but still maintaining the accent color for the other parts of the system.

Mainly it would be for:
- Be able to force black title bars in some apps that have a white title bar even if you are in dark mode.
- Be able to choose the color of the window borders without losing your accent color.
- Be able to choose the color of the inactive title bar depending on whether it is the light/dark theme.

**Describe alternatives you've considered**
It would be doing something similar to what this program does:

**Additional context**
Although what I do is change these registry keys with a script
HKCU\SOFTWARE\Microsoft\Windows\DWM, ColorPrevalence
HKCU\SOFTWARE\Microsoft\Windows\DWM, AccentColor
HKCU\SOFTWARE\Microsoft\Windows\DWM, ColorizationAfterglow
HKCU\SOFTWARE\Microsoft\Windows\DWM, ColorizationColor
HKCU\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Accent, AccentColorMenu
