You can use this to enable the dark variant of your current desktop theme for Atom windows, which results in a much more beautiful interface when using dark UI themes. Note that this currently does not affect the menu bar.
apm install gtk-dark-theme
To enable the dark theme, open the command palette (Shift+Ctrl+P) and select "Gtk Dark Theme: Enable" from the list. To disable the dark theme, open the command palette and select "Gtk Dark Theme: Disable" from the list.
Your current choice will be remembered the next time you open Atom.
