Dark mode in Nimbus notes should be black, and have a dark title bar

Hi, 
In my opinion the notes background should be truly black in dark mode, does anyone else agree?
Or it would be nice to have the option for more than two themes, perhaps there could be a dark theme and a black theme.
Also very obviously I think the title bar should match the theme color! Like it should be dark when the mode is dark. This is rather distracting to look at when it's stark white and the rest of the application is dark.
Thank you for the Wonderful wonderful product :)
