Installing

4. Enjoy a polished dark theme that's easy on your eyes!

Configuring

Brightness suppression

Emails with white backgrounds are made less bright by the theme, to ease your eyes. If you dislike that option, open the file styles/ui-variables.less and change the line

@message-filter-undo:  hue-rotate(-180deg) invert(85%);

to

@message-filter-undo:  hue-rotate(-180deg) invert(100%);

Accent color

It's quite straightforward to replace the orange accent color by another color of your choosing:

• Replace all occurrences of @orange and @orange-prefilter in styles/ui-variables.less.
• Change the color of all orange icons in style/images.

That's it!

ToDo

• Fine-tune for MacOS (Mac users are welcome to contribute :-))
• Include calendar feature, once it's fully operational.
