Enhance ARC lights off experience - dark mode
Is your feature request related to a problem? Please describe.
It would be great to have "lights off" feature in ARC to support dark mode (like Opera has) in connection with Editor Themes that have dark background (like Monokai has). Without this feature the editor has black background and all other portions of ARC unrelated to the edit pane have white background.
Describe the solution you'd like
Apply the same background as in editor pane based on Editor Theme picked in About dialog.
Describe alternatives you've considered
Use dark mode in Opera - however this will solve just colors the browser has itself - not the interns of the ARC page viewed.
Additional context
Dark modes are coming into fashion - honestly - I'm having less eye strain when using black background in text editing.
