Customizing COSMIC: Theming and Applications
(blog.system76.com)
From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

The toolkit decides how their applications look based on whatever theming engines they use. The desktop doesn't have control over that. So GTK applications use GTK themes, libadwaita applications use libadwaita themes, libcosmic applications will use libcosmic themes. We'll try to automatically generate similar-ish GTK/KDE/etc. themes if possible, but it'll depend by what specs those toollkits support in their theming.
