GNOME 3.x has introduced the concept of extensions to allow users to customise their GNOME shell experience. Many of these extensions have not been fully tested with openSUSE. This may include testing the new extensions.gnome.org web service if it is launched during the GCI timescale.

The idea is to download and extensively test publicly available gnome shell extensions and find possible bugs. In this process, the student will learn to read various log files to look for relevant information, and learn a working knowledge of javascript, the language these extensions are written in.
