A custom navbar per user where user can select their favourite features.
To activate it click a NEW link on the main navbar. When activated this changes to an EDIT link on the new navbar. (The NEW NAVIGATION BAR also appears on the profile options.)
User then has a form page with a list of options to place on their very own navbar.
