The dark theme for Linux is broken:

- Some icons have dark background (expected) and black foreground color (that should be replaced by white of very light gray)
- Some icons have light background (not cohesive with the theme).
- The command history shows dark blue font on dark gray background.
- The grid's ruler shows black font over dark background for the numbers.
- The icons folder is missing in the GitHub repository, but other themes have that folder.
- The general icons (open, save, and so on) are not dark theme friendly. A better approach for maybe all the themes would be to use something like the breeze icons pack for LibreOffice, and it will have the added benefit of making the app look more modern.

The icons issue is the biggest problem. They should probably replace the black color for white or very light gray. Even the red accent color is not ideal for dark themes, is not the main issue.

Attached is an image that show the problems and another that shows LibreOffice with the Dark Breeze theme for reference.
