Dark mode (theme) is currently being discussed on https://www.outlinersoftware.com/topics/viewt/9037/30. 

I believe it was last mentioned on this forum https://infoqubeim.com/drupal5/?q=node/4275#comment-20536 in 2018.

 

I'm all for it getting a higher priority. For the programs that have this feature, I'm using dark mode 90% of the time, and it's really helpful with multiple monitors (I have 5 right now, 3 on the desktop and 2 on the laptop).

 

Will we be able eventually to create our own themes?
