Search in Settings
in reaction to your research e-mail with sorting settings into groups, I have an idea. If it is not possible have search field on top of main setting screen like as android settings (I don't know if it is android feature or modification of mobile manufacrurers) or like web browsers on desktop.
I'm not sure about difficult of this idea, but I see that this feature is very useful if you looking for some setting that is using very rarely, or setting very deep in structure, or in another substructure.
If I not not clearly explain I can make screenshots.
