add these buttons with adding columns or filtering options to

• associated views (--> see associated records: you are stuck with the fields defined and no options to add columns or filters temporarily; as you might use the records in different context, there might be a need to adopt the one associated view to the context
• the views on the forms (Account form: showing all contacts (list) and you may want to add a specific contact columns or filters)
• Marketing list / segments --> see all associated records for 'grooming' your list with helps of adding columns spontaneously and filter for them
• maybe even for dashboards (personal or system dashboards)

maybe think about save as... if once the user has created the view she wants to have it saved from there?
