one-dark-shade-ui
Atom One dark UI theme variant, with lower-contrast filesystem tree and other tweaks
One dark Shade UI theme
A dark UI theme, based on the original One dark UI theme, with some subtle, relaxing tweaks.
Tweaks
The main difference between Shade and the original One dark UI is that the filesystem tree gets a lower-contrast styling with de-emphasized icons -- allowing the eyes to focus more on the main editor without competition and distraction.
