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.

I don't get their allure. Why not Tree Style Tabs? You can create "groups" and endless subgroups. Also, no need to scroll horizontally, which takes way longer to find stuff, just scroll vertically or collapse trees.
Tab groups seem inferior to tree style tabs.

Tab groups for the friendly name at the top of a set. Edge implemented vertical tabs. Not as good as tree, but better than across the top.
