installation and settings need to be ckecked before the installer quits
The installer should not just quit without complaining if something essential has been forgotten, like for example right now you can just quit after installing base and a DE but without installing a bootloader (ok, might make sense) or without having created a user or installing a video-driver ... It's quite annoying if you have forgotten something and you have to start over again with installing base and so on. You should be warned at least in that case.
