Bug 419682

I like the stability boost that Plasma has seen in the recent years, but please stop turning (what used to be) KDE into GNOME. 

In comparison to GNOME, KDE used to be highly customizable and powerful. At the beginning it seemed that Plasma lacks many features simply because no-one took time to port them, but after more than 10 years it seems that this was more of a design decision to keep UI simple and intuitive. 

I believe this is the wrong decision. UI in general and specifically of the System Settings module might stay simple by default, but users should be able to configure it to have all the options shown (something as simple and advanced mode in VLC and TexStudio).

There are now bizarre cases with no or very-hacky workarounds such as not being able to change the "week starts with" in calendar widget (#419681), not being able to configure groups (#365787), or very limited options of session management (what happens when you log-out), just to name a few things that all used to be implemented.
