### Problem Description

Developer cannot change caption bar theme. It remains white even if windows theme is set to dark.

### Proposed Solution

When themesource in electron is set to dark, use dwm window attributes or check an example here: [Notepad++ Source code](https://github.com/notepad-plus-plus/notepad-plus-plus/tree/master/PowerEditor/src/DarkMode)

### Alternatives Considered

Check out in Notepad++, Sublime Text, Windows Explorer, MSYS Console...
