System76 is preparing another visual customization feature for its COSMIC Desktop environment. Company CEO Carl Richell has previewed Theme Constellations, a new system of bundled themes that combine wallpapers, colors, icons, and fonts into a single package.
The announcement follows the introduction of the frosted-glass design in COSMIC Desktop 1.3, released in July, which added translucent, blurred surfaces to panels, menus, and other desktop elements.
With Theme Constellations, users will be able to change the desktop’s overall appearance without manually selecting individual wallpapers, icon themes, fonts, and color schemes.
In a short video shared on X, Richell demonstrated the upcoming functionality through COSMIC Settings under Desktop > Appearance. The interface shows a gallery of themes with visual previews, letting users see the available styles before applying them.
The demonstration includes several dark themes with different wallpapers, accent colors, and icon styles. Switching between them changes the desktop’s appearance, including its wallpaper and panel styling.
Additionally, COSMIC already supports keeping transparency effects enabled when windows are maximized through an existing configuration flag. According to Richell, this option still needs to be added to the graphical settings.
For now, System76 has not announced a release date for Theme Constellations or specified which COSMIC Desktop version will introduce it. Richell described it simply as coming soon.
