I decided to install Ubuntu 19 freshly, as it is inevitable, but also that GNOME has promise. However, some things from unity should be inherited without question. One of those things is that you could simply open dash, search the shutdown button, and place that in the dock which is amazing in case of a touchy laptop.
And now years later, a newer system doesn't provide this. You can find the shutdown function in the app menu, but cannot add it as a favorite. Does someone know how to achieve what I want? There are no extensions to be found either.
