Editing Dark Mode & Light Mode Themes Individually

I made a theme yesterday in dark mode since that’s what I primarily use, but the light mode for that theme doesn’t translate well. It would be nice to be able to edit the theme in dark mode and light mode individually so that it translates better for both options.

In addition, I think a function where BetterCampus switches between two themes of the user’s choice depending on the time of day would be cool. :)
