Ironic that Windows has become the same way. New functionality is available first as a Powershell command before the GUI control is written. This is because those are two efforts. First you write the function then you need to call the function from a GUI element.
Ironic #2 is that Pop_OS comes with more settings available in the GUI than any other Linux I have used. Maybe you haven’t tried it.
To say no distro can fix is nonsense. Any distro can make new GUI elements and because it’s open source once the work is done other distros can add the same to their own menus.
Just like it has taken Microsoft over a decade to develop the new settings app, they still haven’t achieved feature parity with the control panel. This should make obvious how much hard work is required.
So the solution is that we just need to write more GUI menus for linux and I’m fine with that. It’s nice to have the option to use a menu or edit the text file. Then everyone gets what they want.
Yes, literally everything you mentioned can be changed in the gui of pop_os. You should really try it before being so confidently incorrect. It’s not a matter of won’t because they already did. They are making improvements all the time.
