If you have read any of my recent articles that touched upon GNOME Shell, of if you use it yourself, you probably know and perhaps already use one or more GNOME Shell Extensions. These extensions are good for many things, from switching Shell themes to adding panel indicators.
GNOME Shell is very much in its infancy now, which means that a frantic development pace is underneath it. Changes, fixes and patches happen at a rate difficult to keep up with. In fact, I have found it difficult to keep track of all the extensions available, understand what they are for, etc.
Fortunately, the hardworking guys at WEBUPD8 have made it easy for all of us to follow their articles on the subject. Simply bookmark the following LINK and you will always stay up to date with all their posts on GNOME Shell Extensions.
