I am starting this task since -according to raster- the config will be rewritten in elm after E18 in order to have a place to start the discussion. Some things need cleanup -in terms of UI/UX of course- other need better grouping, some things need to be redesigned. Of course all this needs to be logical, consistent (to the end user), visually appealing and not hide functionality (we are not gnome 3 after all).
I'll be adding subtasks with various things i have in mind so they can be discussed. Please add your subtasks/ideas and flame your heart out.
