GNOME 3 or as i like to call it 'G3' is the newest release of the Gnome desktop. Many Linux users and distributions are starting to adopt G3 as their default desktop environment because of its look and feel, user-friendliness and performance. But when it comes to customizing, there aren't many options available by default in G3. If you want to do more serious customization on your G3 desktop then you need the Gnome tweak tool.
The Gnome tweak tool is an open source tool developed to customize your G3 beyond normal settings. With this great tool you can make advanced adjustments to various G3 settings including fonts used in the user interface, user interface themes, changes in window management behavior and much more.
