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.

This is an example of a tab group using Sidebery. If you click links on a page that open in new tabs, it creates a sort of folder from the original tab, with the group of links as children of the parent tab. You can also drag them into these groups manually.
Ohh yeah, this is such a must have features. I hope they implement it so that it only appears when the tab is hovered/extended.
