Fedora: 3rd party repositories step missing from initial setup
Fedora has the concept of 3rd party repositories. Users are supposed to be able to find out about these during initial setup and install them.
Testing Fedora 28 yesterday (with GNOME 3.28) I didn't see a step for this. This is a shame because it meant that I was exposed to the sub-optimal info bar to enable 3rd party repositories in Software.
