Most settings applications (GNOME Settings, KDE Control Center) give very limited access to managing lower level components in the system. For example, kernel management, managing groups, etc.
If they did though, in your opinion, what would be the most effective way to offer a simple experience for some users, and more control for those who need it? How would most desktops implement this “hybrid” approach?
Or should users not be able to control those things graphically at all?
The issue here is that the GUI would need to be totally foolproof and needs to cover each and every possible permutation of the system it is supposed to configure.
If you offer a GUI setting, it actually needs to be able to solve every related problem in GUI, so that if you mess up, you don’t have to go into CLI again.
Tbh, I am not sure super advanced settings would work well in GUI. Even in Windows there is a certain level of advancednes of settings, which require you to use regedit or powershell.
