Thanks for the feedback! We are working on this.
Current Dark Mode support: https://docs.microsoft.com/en-us/officeupdates/release-notes-office-for-macthomson_james commented
Would be happy with Reading Pane dark-text-on-light-BG, rest of UI as light-text-on-dark-BG.
Ideally 2 switches; 1 for [Dark Mode], one for [Reading Pane Dark Mode].
Happy for Reading Pane to be in Dark Mode as long as tables don't appear with black text on dark BG?!?
Anything that lets me read the errr... Reading Pane really.
