Reorder items in preferences

i think it would be a really cool idea if you could reorder the items

the application on the right is gnome settings (gnome-control-center)

Thanks @lollilol , I think this would be useful for many people.

I am not sure if I'll have the time to implement this in the near future, so if anyone is willing to start working on this, I'd be happy to help and review your PR!
