We have faced this issue of the bottom dock is not showing up. It only shows itself when you overview the windows or press the super key. This make makes it harder to access the frequently used applications such as file manager, browser, document editor, etc.

Another issue is that the dock that you see is not a good-looking one, it is so big that it ruins the modern look and feel of Gnome. So in this article, I’m gonna guide you to solve both of these issues with the help of an extension.
