• It is possible to display the Opportunities in a 'Opportunity Pipeline View'
• It is also possible to configure the Tooltips that are showed when the user is hovering above an Opportunity in this view (e.g. show 'Estimated Start Date' or 'Volume')
• It is also possible to sort the fields that are shown in this Tooltip (e.g. 'Volume' before 'Estimated Start Date')
• However the Tooltip does not honor the sorting. Instead the fields are displayed in a random order

History: a support ticket was openend for this. Result was that this is expected behaviour.
