In previous Fedora versions, Anaconda offered an "everything" package selection
option.  It would be useful to have a similiar option for people who prefer to
install most (if not all) optional packages.  However, as I remember the
"everything" option didn't allow further individual package unselection.

In order to avoid having to repeatedly click on selection menus, it would be
nice to have an option of selecting all packages (all subcategories, all
optional packages).  But in addition, the user then needs the ability to
unselect specific packages (e.g. different languages).
