Regarding (Regarding the user's edits he refers to iD. iD.)
At the moment you cannot change the way areas are displayed in the iD editor. The [issue is known][1] and sooner or later will be solved by its developers (your help is welcome :) ).
Maybe you want to try another editing program from [the top three][2]. Of course I recommend JOSM but other people say it has a steep learning curve.
