How can we change the order in which our Cabinets display so we can have the most used ones first?
The capacity to re-order the way cabinets are listed is not currently available and this feature has been submitted as an enhancement request.
One way of achieving the result you want is to rename the existing cabinets with a prefix to order them appropriately. For example, add "1." to the first cabinet you want, "2." for the second, and so on.
