I hate to write on a white background, so I usually write my papers in a simple text editor, because I can have a dark background, but it's still annoying not to be able to use LibreOffice advanced features.
Is there a real dark background and/or theme for LibreOffice under Windows? I've got the page background to be dark, and text to be white by messing with the styles, however, there is still a bright white margin border. Any suggestions?
You can modify the application background using the appearance settings (menu Tools → Options → LibreOffice → Appearance):
The "Application Background" is the gray area around the sheets, and the "Document Background" setting affects the entire sheet (margins and editable area). Together with the "Font color" setting, you can modify the appearance entirely without altering the document (page / paragraph / character) styles.
Just as a follow up, I found something you may like too.
Under menu Tools → Personalization, you can now choose a Firefox theme to use for LibreOffice.
Maybe it is worth a look; personally I like it.
In the latest version (6.1), this setting has been moved to menu Tools → Options → Application Colors.
Also, for me, setting Application background didn't have any effect. I had to set Document background.
I was looking for the same features and found the GitHub repository LibreOffice-BreezeDark very useful.
I haven't tried it in Windows (I guess it should work in Windows 10 with the dark theme enabled), but in Linux, if the OS is using a dark background color, you can go to Tools → Options → expand "LibreOffice" in the left panel (if not already) → Accessibility (the third to last item) and check "Automatically detect high contrast mode of operating system".
The background appearance will become dark and the font color will switch to white.
